PAS Fieldtrip to El Chorogo. Part III.

In my previous entries, I posted photos of the specialties found in the forests of El Chorogo (western Panama, Burica Peninsula).  This post will include more widespread species, but also some non-bird inhabitants of these forests.  Two and a half days is probably not enough to discover all what this place has to offer, but we (William Adsett, Antonio Domínguez and your host) were very lucky.  For example, we saw White-crested Coquettes every single day of the expedition, including two gorgeous males feeding in white flowers at the canopy of a tree along the Costa Rica-Panama border trail (in both sides of the trail!).
male White-crested Coquette
That was my first adult male for that species.  I usually see females in the foothills.  Not a common species anywhere!  We did well with the hummingbirds, probably because we found many flowering trees, including many Inga and Salvia sp., attracting Charming, Snowy-bellied and Rufous-tailed Hummingbirds, Long-billed Starthroat, Blue-throated Goldentail, Stripe-throated and Long-billed Hermits, and tons of Crowned Woodnymphs (abundant inside the forest!).  However, our biggest surprise was this White-tipped Sicklebill that hovered in front of me for some seconds!

Although not unexpected, this is probably the first record for El Chorogo.  Always an impressive hummer to watch!  Another impressive sighting were the Great Tinamous' eggs.  Why?  Because they are of a bright turquoise color!
Great Tinamou's nest with four brightly colored eggs
This is weird because most of the neotropical ground-dwelling bird lay cryptic eggs.  Egg color is probably an intra-specific signal for others tinamous; thus, attracting several females to lay its eggs together because a large clutch is less prone to predation than a small, single female-layed clutch, according to a theory.  We found this nest after flushing the male.  We also flushed another ground-dwelling bird during one of our walks:
Marbled Wood-Quail
Yes!  A Marbled Wood-Quail, this individual decided to froze in a branch, looking at us.  It was a member of a small covey that stayed undercover.  They are frequently heard, but rarely seen this well!  Close to campsite, a boreal migrant became one of my almost-lifers: a Louisiana Waterthrush.  One individual was walking along the waterhole deep inside the forest.
My poor photo is due to the light conditions inside the forest... very dark in fact.  In spite of this, you can see the broad, white eyebrow and the buffy flank of this bird.  I also noticed the snowy white throat (with no streaks) and the chip notes that sounded slightly different to the widespread Northern Waterthrush (that we saw outside the forest).  Also close to campsite, we saw some Spot-crowned Euphonias.

In the above photo you can see the "spots", invisible under normal field conditions.  This was the only euphonia found inside the forest, and is restricted to western Panama... specifically to Chiriqui province.  Another Chiriqui-restricted species in Panama, although not a bird, is the Central American Squirrel Monkey.

In fact, this species is restricted mostly to the Burica Peninsula in Panama (see the comment section for details) due to habitat loss in its formal range (more widespread in Costa Rica).  We found several troops, some with more than 30 individuals and with many females carrying youngsters. They are very agile, roaming the treetops with grace and skill.  Of course, we were careful as we watched the canopy. The reason? The inhabitants of the forest floor, like this harmless snake about 5 feet long.
After some research by Bill, we think this was a Pseustes poecilonotus, known by many common names (like Neotropical Bird Snake, Dos Cocorites, and so on...) and highly variable.  We have no idea of the name of this species when we saw it... but had no doubts when we saw the next one:
Fer-de-lance!  This is a pit viper, the main cause of snake envenomation in Panama, where is widespread and well-known by the locals as "Equis" (meaning "X") because of the dorsal pattern resembling the letter X.  Thank God no one stepped on!  
We added more species in the way out the last day of our expedition, like Gray-crowned Yellowthroat and Great Antshrikes, and had great looks of some raptors nicely perched, like this Laughing Falcon atop a towering tree in the middle of pasture lands.

Or this majestic King Vulture that you usually see flying high overhead.  What a great way to end a terrific trip!

The wildlife found in El Chorogo is the most threatened in Panama due to the destruction of all its formal extension, and we have to support the efforts of Panama Audubon Society and some other ONGs (as well as some particulars) to protect it!

Panama's Vultures

The New World Vultures (Cathartidae) are one of the most conspicuous elements of Panama's avifauna... there is always at least one of them within sight field. Misunderstood and usually ignored, they play an important role as scavengers, eating the carcasses of dead animals. They are amazingly adapted for this way of life, and they are so succesfull that most species are essentially aboundant in their own habitat (which includes cities and towns for some species). Sharp eyes and sense of smell, bald heads, effortless long-distant flights, strong gastric juices and to urinate on its legs are just a few of these adaptations.
Of the seven species that compose this family (including two species of extra-limital Condors), four are found in Panama. Of these, the Black Vulture (Coragyps atratus) is certainly the most common. If a panamanian is talking about a Gallinazo or, more commonly, a Gallote; then, he is talking about the Black Vulture. They congregate in incredible huge flocks at their prefered sites, like dumping sites and some beaches, feeding in almost anything they can find. As its name suggest, they are entirely black except for the white primaries which are easily seen in soaring birds.
The Black Vulture is the only member of its genera, the same as the King Vulture (Sarcoramphus papa). This bird is well-named. Not only is the biggest of the vultures (of course I'm not taking into account the condors), it is also quite distinctive from all others due to its mostly white plumage and multicoloured head. Also, it is the first one to eat if there are other vultures' species around a carcass. The numbers of this majestic bird are not even close to that of other species, but anyway it is still common in regions with extensive forest. Despite I have seen this species many times, it is always nice to see it perched (and not soaring as I usually do). This particular individual was taking a sunbath during the first hour of light.
The other two species belong to the genera Cathartes. The most common is the Turkey Vulture (C. aura). The resident subspecies are sedentary birds outnumbered by its black cousins. However, they become aboundant during migration, when most part of the populations breeding in North America fly over the isthmus in an impressive spectacle that marvels both birders and non-birders. The resident group can be distinguished by its pale (white or bluish) nape, and some authors think that they may represent a distinct tropical species... but more studies are needed for sure. At close range, it is obvious why we call them Turkey Vultures... they are pretty evocative of those big game birds worlwide known. In Panama, they are well-known with the local name Noneca; in other regions they are know also as Auras. Young birds exhibit more feathered dark-heads (is the same for all the Cathartes vultures). They have an incredible sense of smell... you can tell by seeing its skull, which have disproportionaly huge cavities to accomodate its sensory organs. Also, they are designed to fly or, more exactly, to soar across huge distances taking advantage of every single breeze, saving as much energy as they can. Its silhouette is distinctive, even from far away!
Finally, the Lesser Yellow-headed Vulture (C. burrovianus) is also pretty common... in the right habitat: swampy savannas and grasslands where they feed mostly on dead fish probably. Despite its commoness, few people is aware of the existence of a yellow-headed (instead of red-headed) vulture, until they get a close look. Then, the bird is impressive, with its rather multicoloured head. One can say that it is beautiful... an adjective not usually used with this family of birds. The Lesser Yellow-headeds usually soar low over the fields, showing its white shafts in the primaries feathers, which separate them from the similar Turkey Vulture. Despite all these vultures occupy different habitats, it is not unusual to see up to three species together at many sites, but more impressive is that, so far, I have seen all the four species together in two places this year. First at El Real airstrip (western Darien province), and then at Flores (southern Veraguas province) where I photographed the King Vulture pictured above. So, always be prepared for the unexpected!

Azuero Parakeets in Flores!

You don't see a panamanian endemic everyday. That is why last sunday was so special. Thanks to an invitation made by Osvaldo Quintero, I went with Gloriela, Rafael Luck and Venicio "Beny" Wilson to the southernmost part of the Veraguas province in the western side of the Azuero Peninsula, to the little town of Flores. Our goal: to relocate the panamanian endemic Azuero Parakeet found for the first time by a birder (that is, not by locals) in that side of the Cerro Hoya mountain range by Beny last april. The only idea of having a chance to watch this bird included mounting an expedition, with lot of hiking and climbing, almost no facilities and really serious logistic headaches (read my journey to Cobachon entry and you'll know what I mean)... until now. We left Panama City during the mid-morning of saturday, june 12th heading west along the Panamerican highway. Osvaldo could not go due to personnal issues, the only negative note about this trip; but under the guiding of Beny we were very confident of our chances (Beny is very modest... he is in fact one of the best guides in Panama). We took the road to Atalaya only a few kilometers before reaching Santiago (Veraguas province's capital city) and then the turn-off to the town of Mariato, which we passed stopping only at the little town of Malena where Beny arranged our rooms and the dinner. Then, we drove to Flores, to the finca of Juan Velásquez, which property includes some forested hills adyacent to the Cerro Hoya National Park. We drove under a heavy rainfall, but somehow we found common species like Great and Cattle Egrets, tons of White Ibises, Red-breasted Blackbirds and Eastern Meadowlarks. A dark bird spotted by Beny turned to be an adult Bare-throated Tiger-Heron. These Tiger-Herons are common along the peninsula's coast, as well in some insular areas (my photo is from El Ciruleo, in the eastern side of the peninsula). The road is very escenic, with impressive beaches and hills. Once at Juan's place, his family welcomed us by saying that the parakeets have been regular during the morning around the house, feeding in fig and nance trees that abound around the property (which have the Playita river and its valley as backyard!). They are present from april to july, the rest of the year they live high in the mountain range according to Juan. The interest of this family in preserving the land for the parakeets (and other wildlife) is admirable. They are constructing a little cabin for the visitors, but until it is finished, Juan is charging $10.00/person for visiting the property, proving to his neighbors that there are others ways to profit that do not involve logging the forest. We spent the night in Malena, after an excellent fish dinner. The next day (sunday, june 13th) we had breakfast at our cabin and started our way to Flores. We drove all the way to the cabin at Juan's property, who accompanied us in our search of the parakeet. The first bird that appeared for photos was a magnificent King Vulture perched atop a tree, having a sunbath. It was a sub-adult because it had some black feathers in the back. That multi-coloured head is something special! We quickly found many birds typical of the pacific slope savanas, like Mouse-colored Tyrannulet, Groove-billed Anis, Bronzed Cowbirds, a pair of Pearl Kites, many Blue Ground-Doves of both sexes and two very special birds: a female Orange-collared Manakin (in a nance tree) and a Black-hooded Antshrike; both of them restricted to the western pacific slope of Panama and southeastern Costa Rica (not exactly in savanas). While admiring the valley of the Playita river and the birds, Juan pointed us a flock of 15 or 16 Azuero Parakeets that flew close to us, passed the car and landed over a fig tree full with fruits (we could have seen the birds from the car!!!). Great! the birds were quietly feeding with the figs, allowing us to take some photos. They stayed for 15 minutes more or less to then fly away inland. We followed Juan while searching the birds, finding them after 15 minutes in a forested area. They were engaged in social activities, as you can see in the short video filmed by Gloriela through Beny's scope with her point-and-shoot camera. Four birds are preening, two of them preening each other intimately! (more and better videos at Beny's YouTube account). We also saw a pair copulating and other ones "kissing" each other.

We enjoyed the birds and its chattering calls, while a Violaceous Trogon was singing nearby. Then, a troop of White-faced Capuchins scared the parakeets, that flew to a nearby nance tree. We relocated again the birds under the vigilance of a Ferruginous Pygmy-Owl that acted as a witness of our joy and happiness. It is always nice to find an owl in the day-time, specially one so cute, don't you think? The parakeets were eating nance this time, very low in the tree an allowing extremely close approaching by us. They were very confident of people, and we got excellent shots of them, both with our DSLR's and by digiscoping (Gloriela is much better than me in that technique because she always does "digimicroscoping" at her work). What a glorious moment, and what a cooperative flock of birds. I don't know if they were as curious as we were. The birds flew to another nance tree in a nearby hill. It is a real spectacle to see a flock of these birds flying with their blue flight feathers and red tails and rumps. They looked like tiny Great Green Macaws, that also occur in the area, but not that day. We reluctantly said good-bye to Juan and his family, finding a different flock of 5 or 6 parakeets close to their house (confirming Juan's statement of the coexistence of several flocks in the area). It was a long way to Panama City, again under a heavy rainfall most of the way. Still we are thrilled by the experience! Thank you Beny for showing us the easy way to see one of Panama's most extraordinary endemics. If you still need that bird, or simply want to see it again, don't hesitate to contact Beny, it is a great experience!
