Enjoyed the birding stories and all of the pics.

I had a hummingbird feeder up near McClure for years. There were mostly green hummingbirds with an occasional brown one. Every year, around early fall, the yellow jackets would become territorial and take over the bird feeder. One or two of them would sit on the feeder and keep the hummingbirds at bay. One day, I was sitting near the feeder. I could hear a loud hummingbird in a nearby tree. Eventually, he flew to the feeder and stopped about 18 inches away from it. The yellow jacket got off the feeder and faced the hummingbird. They were about 6 inches apart and facing each other. They started flying sideways keeping the same formation. They would stop, start, go forward and backwards in formation. They then started doing this at a high rate of speed. The yellow jacket matched every move the hummingbird made and vice versa. This went on for a couple minutes, then they disappeared into the trees. A few minutes later, a hummingbird returned and started feeding. Soon, a few more hummingbirds joined him.

No idea who won the battle or even if the hummingbird that returned was the same one who faced off with the yellow jacket. I never saw any dead hummingbirds when the yellow jackets were in the territorial mode.

One spring, I found the feeder pieces on the ground and the bottle empty. I suspected the local kids and eyed them with suspicion when they would walk by. I wired the feeder up with safety wire. Even with the wire, I could tell that the feeder was being tampered with. I watched the kids closer but they did not look mischievous or conspiratorial. One day, I heard loud squawking in the yard. I looked out to see an oriole fighting with the feeder. He would physically attack the feeder. When it tilted, he would try to get the liquid that spilled out. He emptied the feeder in short order. I ended up setting up an oriole feeder to both the orioles and hummingbirds.

- Don't go past tense quite yet. I still have a lot of work to do on T&T. And I've always felt bad about hardly reporting at all on Belize. Hoping I'll be able to get something done with that with this current push.

- Beaucoup thanks to all the photographers whose work I'm pirating to illustrate the trip. Back in the days of film I used to play that game not all that badly but now I'd much rather take in the experience at the time and search for quality shots of what I was seeing.

When your post appeared I was working on one blasting that style of feeder. Stay tuned.

2017/01/05 transfer from Trinidad to Tobago, Castara, Naturalist Beach Resort, first room - ground level, bottom right. Wi-Fi reception substantially sucks.

2017/01/08 get transferred to the Tuna Room - up the steps to the second floor, around the back, far corner. Wi-Fi not bad.

Hanging over the walkway railing in front of the room:

'cept empty, filthy, missing a bee guard, obviously hasn't been used in years. I spend about an hour taking it down, thoroughly cleaning and reassembling it, stowing it in a closet where hopefully no one will ever disturb it again.

Assuming all components present - fourteen parts.

Image

Three parts. Cleans in no time. I use a soapy toothbrush to scrub the three ports.

Also, the Aspects, Inc. job has an ant moat built into the main/dish component. So to be fair we need to amend the Perky Pet job with:

http://www.duncraft.com/Stokes-Ant-Moat?ref=CJ
Image

and up the count to fifteen.

The inverted bottle design feeders have a couple of rather negligible items in the arguably plus column:
- You can design them for pretty much any capacity you want.
- The sugar water level stays constant at hummer bill/tongue position.

But aside from the aforementioned maintenance nightmare issue...

When things cool off (at night in particular) the air and liquid volumes contract and cool air is sucked up into the bottle - along with hapless insects in the wrong place at the wrong time. And when direct sunlight does its thing the fluids expand and sugar water is pumped out of the ports - unless the hummers have been able to maintain an adequate pace.

Ant moats can be rather necessary components - 'specially when word has gotten out to a Carpenter Ant colony - but I hesitate to fill them 'cause they tend to drown lotsa innocent victims. For many past seasons here at home I haven't needed to and have been able to release a lot of trapped bugs unharmed.

And I just discovered and ordered a set of:

http://www.aspectsinc.com/01_PRODUCTS/384_NectarGuard.html
ImageImage
http://birdfeeding.com/nectarguardtips-12perpack.aspx

It'll be several months before I get an opportunity to test fly them. (Pretty sure the bats wouldn't be very fond of them though.)

Had toyed with the idea of bringing one of my Aspects Inc. feeders with me to Belize, really regretted not have - 'specially during the stay at the Crystal Paradise Resort. This time...

Hadn't wanted to take sugar with me for two reasons:
- like taking more rabbits to Australia - just in case
- superficial similarity to cocaine

Paper packets of raw (brown) granulated sugar are ubiquitous all over T&T, the white more refined stuff is uncommon. Swiped half a dozen packets from the Naturalist Beach Resort breakfast "room" and went to work upstairs. Found the stuff to be so sticky that I had to dissolve it in water to utilize more than twenty percent of the two packets of Effort One. Solution itself, not surprisingly, had a brown tinge.

Bananaquits and tanagers had noticed within a couple minutes but had to remove the lid for periods to give them shots. Hummers were on the scene shortly after the passerines but wouldn't sip. Wouldn't sip all fuckin' day.

As the daylight faded I became bummed out by the failure of my efforts but my mood shifted radically when I stepped out after dark and found the place swarming with my Lesser Long-Tongued Bat buddies.

Began suspecting the raw sugar and did the homework I should've before. Basically, the stuff's cheap dirty crap. It's sticky because of a molasses content and you're not supposed to offer it to hummers because it's high in iron (along with other minerals). Hummers have access to zilch in the way of iron in the course of normal natural feeding so they hoard what little comes their way. Give 'em lots of it and they hoard it to toxic levels.

Shit!
- Glad the hummers weren't doing my feeder.
- Maybe they were able to recognize the bad stuff.

Let the bats finish off the feeder. (Took the lid off when the level was close to zilch. Dish was pretty clean by daylight.) The same iron issue well might also have applied to them but figured I probably wasn't gonna kill anybody with two packets worth distributed amongst small flocks of birds and mammals over the course of a sixteen hour period.

Had a couple packets of the normal/white/good stuff from the Caribbean Kitchen and made my next batch from that. But still had hummers coming in - Copper, White-Necked Jacobin, Rufous-Breasted Hermit, Ruby-Topaz - but never so much as physical contact with the feeder. Some approaches were investigative, most were to defend the resource that none of them were exploiting. Don't think there were any other feeders in the neighborhood closer than the ones at the Caribbean Kitchen - about 330 hummer flight yards down the beach and up the cliff.

World's second smallest bird - after the Bee Hummingbird of the Cuban Archipelago. First one I got was at Asa Wright below the veranda working some vervain...


Image
Steve Garvie

...a couple of feet from my face.

Don't seem to show much (any?) interest in feeders. Too bad, I'd have loved to have landed one.

Was told that their bills are too short for the task. Don't put much stock in that explanation 'cause the Bananaquits - which suck at sucking - go totally nuts...

http://www.bochnik.com/trinidad/trinidad2016.htm
Image
http://www.bochnik.com/trinidad/feedfrenzy1470.JPG

...when a feeder is refilled to the brim. But:
- lotsa comments about them being scarce at the feeders
- photos of them at feeders seem to be nonexistent

Hummers are a little tough to land at Asa Wright. They have a zillion feeders on and in close proximity to the veranda and if a big monkey with fingers at perch positions makes them the slightest bit nervous it's usually not much of a big fuckin' deal to shift five feet left or right to another option. One could always get them in time but it takes extra time (duh) and it's tiring and uncomfortable too maintain position and minimize movement for longer periods. In Idaho where I had the luxury of zillions of hummers majorly worried about each other and just one feeder... Spoiled rotten.

One afternoon I became so bold as to unhook a feeder and rest it on the deck railing. Infinitely more comfortable. And the more monkeys there are stationed at feeders the more of a pain it is to avoid them and the more part of the normal background they become. A couple other revolutionaries were following my lead and our efficiency almost instantly quadrupled.

So, of course, in the name of humanity's never ending pursuit of mediocrity, AWNC Guide Barry comes along and, with a proclamation of "Poor form." breaks things up and kills all the potential for peak experiences.

I bite my lip and do not say...

- Poor form? Tell me how this is "poor form", motherfucker. Tell me what harm is being done, how anyone or anything is being hurt by this activity. Search the web and show me a single instance or example of an actual downside.

- Wanna talk poor form? How 'bout when you guys take all these groups out on the trails and play recordings of territorial and predator calls to get your target species all worked up and in close?

- For that matter, how 'bout all the CO2 we're pumping into the atmosphere to get to, from, around in these places? If we're gonna be doing it in the first place we'd better be spending as much time as possible making the most of things.

Similar experience with the bats. Night and Dawn One I got them hand feeding, making contact. Guide Jesse told me after breakfast that he was also a bat freak from early childhood, nobody had ever done that before, he'd have been afraid to try it. It was an absolute blast for me. I had made plans for what I'd be doing every evening and dawn for the rest of our stay.

The next evening as the bat cycle was phasing in the staff was busy emptying and rinsing hummer feeders and not restocking fruit feeders. Barry said AWNC policy was to NOT attract bats, that they needed to disperse and forage naturally in the forest (cold turkey). (Why? 'Cause they're not brilliantly, dazzlingly colored and freak out fifteen percent of your staff and guests and visitors and prospective guests and visitors?)

And I'm thinking that without breaking any rules and with an AWNC Guide totally cool with what I was doing I'd single handedly served as the catalyst for an end to gawd knows how many decades of policy regarding these nocturnal hummingmammals and the AWNC experience will be substantially diminished for untold tens of thousands of guests and visitors until the end of time.

So I lay low for a couple days until I have a good opportunity to sidle up to Jesse when he's isolated on the veranda. Keep a poker face, eyes aimed out at the valley, quietly say, "Looks like I'll also be the LAST person to hand feed the bats at Asa Wright."

Quiet response, poker faced, eyes aimed out at the valley, words to the effect of: Nah, we'll be doing the hummer and fruit feeders for the night action. "Barry can be like that sometimes."

And the hummer and fruit feeders get replenished for night action by staff and Yours Truly gets another good contact experience down below but doesn't say anything about it later.

Obviously some power play, political stuff going on behind the scenes. Thought Barry was a bit of a pain regarding those couple issues but don't have him in my total asshole column. But if you're gonna tell me "bad form" on something like that you better follow it up with an explanation as to WHY - rather than just making a declaration I'm supposed to accept just 'cause you declared it. That's just total bullshit. When they tell ya not to feed the bears at the National Parks in the US - even though the reasons should be pretty fucking obvious to everyone and his dog by now - they follow up with the reasons and make it an educational opportunity.

Evening One I'd seen a bat in the veranda space on a north heading disappear and commented that they didn't seem to be very shy about going into the building.

Evening Two we were in the living room watching an Asa Wright orientation video. The instant it began discussing the bats one whizzed by my right ear. Right on cue. Wondered if it was something he practiced a lot.

Rum punch before dinner...

http://www.bochnik.com/trinidad/trinidad2016.htm
Image
http://www.bochnik.com/trinidad/rumpunch1250.JPG

...at events, on some off-site excursions is an Asa Wright "thing". One evening, New Year's Eve maybe, one of the staff is doing rum punch waitress duty on the veranda. About once a minute you'd hear her screech as a bat would pull up a few inches in front of her face upon conclusion of a low level reconnaissance run over her serving tray. "Fire her and give me her job!"

Unattended reserves of rum punch rations on the counter are covered by a red cloth to keep the bats at bay. The bats land at the edges and try to figure out how to get underneath and to the sources of the irresistible aromas.

Couldn't land any Bananaquits. Figured they'd be brain dead easy when I first encountered them. Sugar junkies, come in close to people on feeders, not shy about coming inside and landing on occupied meal tables foraging for goodies. Settled for closing this thirteen inch MacBook Pro, sprinkling some raw sugar bits on the center, having a finger on the laptop while one of the guys took the bait.

Guess when your power to weight ratio and maneuverability go down and your reaction time increases your wariness level tends to rise.

Got the Nectar Guard Tips in today's mail. Damn, they don't fit my feeder. The web site DID only list the mid sized / 12 ounce version of my model as compatible but it would've been nice if they'd warned that it didn't fit anything that wasn't specifically listed. Oh well...

When you're trying to land hummers it helps a lot to either have fingers in perch position in front of all ports or in front of some ports with others disabled. My HummZinger Classic Mini / 8 ounce has three ports I can just about get my fingers around but I've got a couple of nylon machine screws and nuts I can use to turn it into a single porter. (Used them to force my Ruby-Throats into optimal viewing position when I had it hanging outside the window.) And all the T&T feeders I encountered were higher volume and larger diameter.

And while I was down there I was thinking that it would be nice to have a small diameter feeder - maybe something geared specifically for hand feeding. Then a couple days ago I found out that I wasn't the first person to ever come up with an idea like that.

Something that I picked up in T&T that I'm kicking myself for not having thought of independently many years ago...

For some period at Ridgely we had a flyer who was also a serious astronomy geek. He drove a pickup which was essentially a platform for a serious telescope setup and the center of the Delmarva Peninsula had a pretty good (dark) night sky. And he showed us lotsa really cool stuff out in the solar system and beyond.

Had a green laser to guide us around. It was a three hundred dollar toy and we'd never seen anything like it. I wanted one.

A few years later the price had come down about ninety percent and I got one to take on camping trips in Idaho with my sister's family. And now they're approaching dime a dozen level on eBay.

Traditionally when birding in a group and there's something good parked or flitting around in the canopy you get or give a description of trees, limbs, branches, foliage to help zero in. See where I'm going with this?

I was kinda pissed off that only the guides had lasers and that they didn't provide loaners, offer lasers for purchase, advise visitors to bring them 'cause there's nothing carved in stone that says that only a guide can have a bird worth locating for others. I've got an eight dollar spare due to show up in the mail shortly.

A word on safety regarding these five milliwatt jobs... I was playing with my first one on the first night, shooting into the trees, and then thought, "What if I hit a Flying Squirrel." Read up on this issue and found that you needed to heat retinal cells to the point of destruction to damage vision. Staring into a beam for a few seconds isn't gonna do anything and a momentary flash in an eye is gonna do even less.

Toldyaso.

It'll be a while before I'll be able to test fly them. You'll get a few Rufousses overwintering at feeders in this neck of the woods but the Ruby-Throats won't be heading back north any time soon and it was a real bitch to land them years ago when I made that a project. Kinda few and far between, adult male staking out the area and making sure nobody else got anything.

Spare laser pointer made it to the local post office this morning at 06:27 local and is now listed as out for delivery.

My first laser went on the fritz after maybe five years, devolved into a weird flashlight. I'd read some reviews on the current crop of cheapos. In addition to them dying after the first ten minutes, not working out of the box I found a complaint or two that they were useless in the cold. Laser 2 went into the freezer for an hour yesterday afternoon and emitted a dim red glow when I pushed the button.

Thought that that was weird 'cause most electrical / electronic devices like the cold. Figured it must be the batteries - NiMH - and quickly popped out and tested them. Tested fine. Warmed everything up under my jacket and layers, things started humming better but for a while I was seeing a laser dot in the middle of a disk of scatter. Thought it was permanently partially trashed but after some more warming time it got back to normal.

Birders do lotsa cold at this latitude and astronomers LIKE cold 'cause it freezes the moisture out of the bothersome atmosphere. Not a limitation about which many users should be very happy. Hoping I'll be able to stay functional when I need to by stowing it under clothing in the field.

Got my hands on the laser a little bit after noon Saturday. Works, fast spreading beam, lotsa scatter. Predecessor was much better. Did the searching and research I should've before blowing the eight bucks. Short story - the ubiquitous 532 nm wavelength jobs are cheap junk. And none of them handle cold. May spring a dozen times that to get a quality 520 nm toy. But these'll do well enough for locating birds.

The Scarlet Ibis thrill riders get packed into the boats like sardines. Our Asa Wright Gang of Four goes in a separate boat with two guides - Roodal and a Nanan descendant (who runs the boat). We get briefed about mangrove ecology and take our time getting to the main Ibis viewing lagoon - Tree Boa; Parrotlets; Tropical Screech Owl; Green, Tricolored, Little Blue Herons; Snowy Egrets...

Then we park out near the west edge of the target lagoon along with the dozen thrill ride boats already in position, sun going down behind us, great lighting, and watch all the stuff coming in to roost for the night - mostly Snowy Egrets and Ibises.

Flock after flock after flock... Ya feel a little dirty. There's zillions of these things, you've already seen several before you get on the boat, you know you're gonna see zillions - as do all the scores of regular tourists, they're gonna come in like clockwork...

http://caligo.com/
Image

But it IS spectacular, the birds are stunning, and it's something you've GOTTA do if you're down there.

I am glad, however, that nobody's making me choose between the Scarlet Ibis thrill ride and being the only individual who watched a Bat Falcon dive on a Greater Bulldog Bat fishing on the waves of Grande Riviere Bay near the eastern extent of the Caribbean Sea a bit after sunset on 2017/01/04. In the processes of doing research and harvesting representative photos for these posts I've found NOTHING WHATSOEVER relating to these bats and this phenomenon. (I told a housekeeper at the Mount Plaisir Estate Hotel what I'd seen on Evening One and she insisted I'd been seeing birds until after I shoved a YouTube video in her face.)

And you'll note I haven't been able to illustrate the relevant post with a photo of a Greater Bulldog Bat fishing the ocean waves - let alone one doing same and being attacked by a Bat Falcon. Come to think about it... It doesn't speak real well about the overly avian focused ecotourism industry down there that the Grande Riviere Bay Bulldog Bats aren't a regular tour highlight.

On the trip back out of the swamp there was the same two day old crescent moon everybody else on half the planet was seeing but from a latitude of 10°36'19.15" N it was diving nose first straight freaking down - instead of being cocked at an angle the way we temperate / mid latitude folk are used to seeing it - followed by a brightly blazing Venus. Pretty cool.

Thanks...
You're way more than welcome. Putting a lot of work into them - most of it going into finding good representative photos.

Fortunately, with respect to that issue, birding/ecotourism is a major industry for T&T and anyone booked for organized exploration will follow in the footsteps of untold tens of thousands of previous similarly motivated individuals. (We were virtually always crossing and recrossing paths with fellow binoculars slingers we'd met previously - all over the freakin' islands.) And in this amazing and explosive digital age...
But no confirmed observations...
Nah, we were the better part of two thousand miles northwest of its range.

Confession regarding hand feeding the Long-Tongued Bats... As reported earlier these guys feeding on fruit look like wolves attacking a caribou carcass. Pretty scary looking but I figured out pretty fast that I was in no danger of getting bitten by mistake. But on my last effort...

Between the nail and first knuckle of my right (I think it was) middle finger I had a small boil/blister. Somebody lightly investigated it with his teeth - just hard enough for me to get the mildest of a pricking sensation. I ran the factors through my head and figured that I would be in much greater danger of being killed by an asteroid than developing a case of rabies and decided I wouldn't do anything or worry (much) about it.

Then shortly after getting back home I developed a fever, sore throat, headache. The rational part of my brain told me that this was something I picked up from some human on a plane but I was a pretty happy camper when I was fully recovered maybe 36 hours after the symptoms first started manifesting themselves.

I'd remembered a piece I'd heard on NPR a couple/few years prior about some of the common wisdom about rabies - that you get infected, the virus works its way up the nervous system from the bite point to your brain, if you're not vaccinated soon enough before it gets to your brain you die a horrible death - being crap.

They said that amongst the indigenous human population of Trinidad there were lotsa individuals who were testing positive for rabies antibodies. They're getting fed on and infected by Common Vampire Bats (Desmodus rotundus)...

I'd continue hand feeding my little hummer bats - given the opportunity. But I'd probably cover any "interesting" irregularities on my fingers with patches of masking tape first.
