Walking the Pipeline Road

I'm back from an early visit to Gamboa and Pipeline road (central Panama) this morning with Osvaldo Quintero. As usual, we started at the Gamboa Ammo Dump, where the activity was great, with lots of common birds in the surroundings. Among the flycatchers, the chachalacas, and the jacanas, we found a cooperative pair of Barred Antshrikes feeding at eye level. Curiously, these are the first individuals of this species that I see this year, despite they are pretty common in the city (and perhaps elsewhere). I really like its call, a ba-ta-ra-ra-rarara-RA! frequently heard, and the origin of the spanish name for the group (Batará). Many people think that the female is prettier than the black-&-white male, what do you think? Close to them, two or probably three Buff-breasted Wrens were skulking, giving loud notes eventually... they were simply too shy for my camera! We left the Ammo Dump and headed to the entrance of Pipeline road, where a huge fallen trunk blocked it. We had to left the car in the entrance and started to walk the first part, which usually we by-pass to go directly to the Juan Grande bridge or to the Panama Rainforest Discovery Center (PRDC). It was a good think actually, because we got some others birds in the short walk, and we also joined Jennifer Wolcott who arrived earlier to the road. We found a group of skulkiers in the undergrowth, including Dusky Antbirds, Dot-winged Antwrens and a Black-bellied Wren that I barely captured with my camera... you can have an idea of the tangled and dark habitat this wren prefers by looking at the photo. In an area with tall grass (where we never stop with the car), I detected little activity in some vains, it was a warbler and I managed to take these photos (you can enlarge them):

Not the best photos (Osvaldo's are much better), but at least you can see the mostly bright yellow underparts with white vent and undertail coverts and the narrow black line through the eye of a Blue-winged Warbler, another rare warbler for this season's collection! In the field was very evident its two white wing bars over the blue wings. It was foraging alone, despite there were two Squirrel Cuckoos and several Lesser Greenlets close to it. The cuckoos stayed for photos, the warbler did not. It is so nice to have such a gorgeous and big cuckoo as a common species in Panama. We walked beyond the Juan Grande bridge, but we only heard more antwrens, some fruitcrows and a pair of Black-breasted Puffbirds, so we decided to walk to the Rainforest Discovery Center. Good choice because the activity was crazy there, both of birds and people... several birders and non-birders groups were in the Center, even George Angehr (author of the new field guide to the birds of Panama) arrived there later. After saying hello to the staff, and after having some sodas and a snack, we started birding the surroundings. A huge mixed flock was passing by, with Yellow, Bay-breasted, Chestnut-sided and Golden-winged Warblers, Brown-capped Tyrannulet in a Cecropia tree (usually only heard, this is a canopy-dweller, tiny flycatcher), White-winged Becard, Dot-winged Antwren, another Black-bellied Wren and several Scarlet-rumped Caciques. We heard the characteristic call of a Moustached Antwren, and after a quick search we found him with the flock high in the canopy.... again, only marginal photos of this tiny, but attractive bird. At the end, it was worth the effort to walk into the road, instead of driving it.

Birds bonanza in Metro Park

Yesterday, I went to the Metropolitan Natural Park following the directions of Osvaldo Quintero who told me that the trees at the lookout were full with fruits and birds since the last week. I just wanted to see what it was all about up there so my plan was to walk without resting all the way to the lookout, which is at 135 meters above sea level in Cedro hill. I took the Mono Tití trail because is wider and fresher than La Cieneguita trail, which starts behind the rangers' station. Of course, my plan of walk directly to the lookout without stopping on route was quickly interrupted due to bird activity. Close to the first lookout (in the way up), a dead trunk attracted three different couples of birds: one of Crimson-crested Woodpeckers, other of Lineated Woodpeckers and a pair of Orange-chinned Parakeets excavating a nest in a termite nest... all in the same trunk. Both pairs of woodpeckers were working in different branches, ripping apart and throwing huge pieces of bark from the trunk while looking for worms and other insects, without agressions or shouts, everything in harmony. The parakeets stopped what they were doing to have a look at me, they are so curious! The understory that surrounded some fallen branches and roots of the dead trunk was also alive in birds. A pair of Fasciated Antshrikes were inspecting every corner while a Dusky Antbird sang from a cover. It is fascinating how a dead trunk have so many niches to occupy. Back on route, I started to hear the flocks of birds while approaching the lookout. And then I realized why... many of the trees bordering the lookout were full in fruits, just like Osvaldo told me. Many species were taking advantage of this, not only the frugivores, but also many insectivores as well. I also noticed lots of butterflies and other insects in the area, and many mammals too (more about them in my next post). I simply sat down and waited. The birds appeared in waves. First a flock (yes, a flock) of Tropical Kingbirds, more or less 20 birds eating fruits and flycatching, accompanied by one, possible two Dusky-capped Flycatchers. Also, many Yellow-green Vireos were feeding at the trees, probably preparing themselves for their journey to South America. The frugivores were represented by Blue-gray, Palm, White-shouldered and Plain-colored Tanagers and also Blue Dacnises. Even a Squirrel Cuckoo showed up, also eating fruits! Then, I found a single Double-toothed Kite nicely perched just below the canopy. At first, it was far away, but got closer while following a troop of Geoffrey's Tamarins. That was not the first time that I see those kites following monkeys. If you have any doubt about why they are called double-toothed, check the close-up that I made of its head. A mixed flock of swifts and swallows patrolled the air over the lookout, with Short-tailed and Vaux's Swifts, and Gray-breasted Martins. Sometimes, they were so close that I thought they were going to hit me! I spent more or less three hours at the lookout! In the way out, I checked the spot of the Common Potoo reported elsewhere, finding only the downy fledging acting already as an adult potoo... it is not the cuttest thing?
