We are wrapping up the breeding bird count season in Costa Rica. If I could do a few counts a week, I would but I only do three because I haven’t had time to do more. Hopefully, that will change by next year and I can participate in counts on the Osa (where a cool count workshop took place this year), on the Manuel Brenes Road, and other birdy spots. In the meantime, I enjoy my three counts; one near the house, another on Poas, and the third one at Quebrada Gonzalez, the first place that acted as my inaugural birding experience in rainforest.
Since that day in late 1992, some of the bird populations at the site have changed somewhat and not for the better. The habitat is there but the amount of rainfall that resulted in massive mixed flocks, hawk-eagles, tons of wrens, and various foothill specialties has diminished. Most species still seem present but several have declined bit by bit in conjunction with less rainfall, and a few species might be gone from the site. They might still show up from time to time but have most likely taken a hike to higher, wetter, and cooler elevations.
But this post is about the most recent count, not laments over human-caused climate change that is pushing so much life towards extinction, so I will get on with the report. Fortunately, Susan was able to join me for the count, and we started at 6 am as usual. The gate is usually closed until 8 but, thankfully, I was able to speak with the rangers and arrange an earlier visit. Our first point was busy straight away and ended up being the best of the day because we connected with a mixed flock that held White-throated Shrike-Tanager, several Carmiol’s and Dusky-faced Tanagers, and other birds.
The excitement almost stopped there because most of the following counts were pretty slow. We had just a couple Black-headed Nightingale-Thrushes, one or two Dull-mantled Antbirds, one White-ruffed Manakin, and low numbers overall. The Lattice-tailed Trogons weren’t calling, nor were the Chestnut-backed Antbirds, but we did have several wood-wrens and Stripe-breasted Wrens, one Band-backed Wren, and a fair number of other species.
Although it was a bit slow, that can always happen at that site with one or a few rare birds thrown in for good measure. This happened during the count as we got our best bird up on the ridge at one of our points. As Susan looked up, she noticed a bit of movement and said, “There’s a raptor” followed by, “wait, is that a raptor”? I got on the bird and yes, it sure was and a good one. For a moment, she wasn’t entirely sure about it being a raptor because it was so small. That could only mean one thing, Tiny Hawk!
We watched it for several minutes in the subcanopy as it plucked the feathers from and ate some small green bird. This was a fantastic sighting because although I have always known that the species was present (perfect habitat and other reports), this was the first time I had actually seen it at the site. This mini hawk escapes detection because it is probably naturally rare, is the size of a thrush, happens to be a sneaky ambush predator that hides in the dense vegetation of the canopy, and doesn’t vocalize that often. In other words, good luck seeing it!
After the Tiny Hawk, we also flushed a juvenile Olive-backed Quail-Dove. This species seems to be getting more common at Quebrada and might be out-competing the formerly common Purplish-backed Quail-Dove.
On the other side of the road, things were pretty quiet with almost no birds visible from the overlook. It wasn’t really until after the count that we started getting more species. A Chestnut-backed Antbird finally sang, we heard a Dot-winged Antwren, two Streak-chested Antpittas, and had a juvenile Great Black Hawk fly right into our field of view.
Kind of a quiet morning, but at least one flock during a point count, a bigger one between points, and a few other forest species that are tough to see. Not bad for a morning of birding and pretty much par for the course at Quebrada. Stay longer, just hang out in the forest, and you might be surprised at what shows up.
