Random stops along Panama City coast

The modern and busy Panama City offers more than lush and cheap shopping, it offers the chance to watch thousands of waders and other aquatic species without much effort.  Some days ago, I visited several sites along the coast just to see what can I find.  My first stop was at the west bank of the Panama Canal, at Farfan.  This site is opposite to the Amador Causeway, where the Biomuseo is now an iconic symbol (designed by Frank Gehry).

There is a huge pond just next to the beach, surrounded by a dike with overgrown vegetation.  I was able to walk along this dike for some sections.  There were many shorebirds species, including this Lesser Yellowlegs (that was not shy at all).

I was interested in the ducks, since this site produced in the past some very rare species and this season some rare ones were reported too.  I saw several groups of Blue-winged Teals, which is the commonest wintering duck in Panama.  There were some individuals far away in the other side of the pond that I was unable to ID, but certainly they were teals too.

One of these groups of teals included seven Lesser Scaups as well... can you separate them?

I also saw a weird concentration of Franklin's Gulls resting in this pond.  The Franklin's Gull is a common passage migrant, but quite uncommon as winter resident.  I counted no less than 35 individuals, including this first-winter individual.  Notice the white outer tail feathers, broad eye crescents, white underparts and pale inner primaries.

Then I moved to Panama Viejo.  The number of Laughing Gulls was impressive... and there were also some Franklin's Gulls with them.  Notice the difference in wing patterns and general shape/size of the two flying adults in basic plumage.

I also saw a very distant Lesser Black-backed Gull among the Laughings and several terns species... too distant for photos.  But several other species were close enough to appreciate well, like this Wood Stork.  Panama Viejo is a regular spot for them in the city and, as you can see, they can be effective as pest control. What major city in the world has no rat problem?

Nearby, a flock of elegant Black-necked Stilts was feeding in the exposed mudflats.  They are found year-round in this site and are beautifully patterned in black and white with long, pink legs.  They are even more elegant when flying.

But nothing compares to the elegance of the American Avocet... and a pair seems to be wintering right there in Panama Viejo!  One individual literally materialized in front of me, close enough for some shots.  It was feeding in the water.  When it flew again, I noticed something rarely seen... its curious pink toes.

Nice collection of birds along our coast!

Bird of the Month: American Avocet

The American Avocet (Recurvirostra americana) is an elegant wading bird beautifully patterned in black and white that breeds in North America and winters principally in western North America, Mexico and the Caribbean.  In Panama, it is considered a vagrant... recorded only in few winters.  It has an unmistakable profile, with its long legs and upturned bill.

During the breeding season, they get a cinnamon color to the neck and head.  As fas as I know, this plumage has been seen only once in Panama, back in 2012 when a group of these birds stayed long enough to molt into it right here (the photo above was taken in Costa del Este, Panama City in May 2012).  However, the basic plumaged birds are quite attractive too.

The American Avocet belongs to the Recurvirostridae family, which consists of three genera and only seven to nine species depending on how many Stilts do you recognize as full species.  Avocets and stilts share the same elegant profile of slim bodies and long legs and are found often together exploiting the same habitat in spite of the different shape of their beaks.
American Avocet and Black-necked Stilt
This season, a pair of these delicate birds is wintering in Panama Viejo (Panama City), and I invite anyone still needing it for its life or country life list to visit them.  For these, and many other reasons is why we chose the American Avocet as our Bird of the Month!

It does exist! A forest elf

Some bird species are so rare and seldom reported that you usually don't think on them... even when you visit the adequate habitat, they aren't in your radar and, in fact, you think of them as myths... until you find them!  Osvaldo Quintero, Rafael Luck and I had that experience today in Altos del María, an exclusive development in the foothills of Panamá Oeste province, above the town of Sorá.  The truth is that we were seeking for some rare sparrows reported elsewhere and started checking some open habitats near a park at the valley.  Soon we found common species, like Tropical Kingbirds, Streaked and Social Flycatchers, Palm, Blue-gray, Crimson-backed, Plain-colored, Summer and Hepatic Tanagers, Snowy-bellied Hummingbirds (and a Long-billed Starthroat), Black-throated Green, Rufous-capped and Tennessee Warblers.

Soon we realized that our search was in vain and decided to move to a better area close to the Valle Bonito lake.  One of the best trails in Panama starts there, running along a rushing stream (crossing it several times) and then climbing all the way up to the Continental Divide.
Valle Bonito lake (notice the sidewalk entering the forest)
My friend Alfred Raab, an Altos resident, told me that he had seen one of my nemesis bird along this trail (Dull-mantled Antbird)... my expectations were low... after all, it is my nemesis... and if you think I finally found my nemesis based on the title of this post... then you are wrong.  No, I didn't find the Dull-mantled Antbird... the trail was very quiet and we only found a little mixed flock at the beginning of the trail with some wintering warblers (Blackburnian and Canada), Carmiol's Tanagers, Slate-colored Grosbeaks and a Plain Xenops.

After the 1 km mark on the trail, we flushed from the ground a medium-sized bird that perched at eye-level merely 2 meters from us.  It was in a dark spot, but close enough to see every detail with my binoculars... I could barely believe my eyes: a long-legged, tailless little forest elf... a Scaled Antpitta.  After a few seconds (after recovering from my shock) I was able to show it to Osvaldo and Rafael.  Then, I remembered that I had my camera in hand ... adjusted the setting and took a single photo:
SCALED ANTPITTA!!!
Hey, I know it is an awful photo, heavily edited to at least show the pale moustache and postocular spot, but the general jizz is evident (it looks better if you move away a few steps from the screen).  After all it is my life Scaled Antpitta!  This is a VERY rare species in Panama, and I do not know if it had been recorded before in that area (although the most recent records come from nearby El Valle and Cerro Gaital -you can check the Xenornis reports here-).  Osvaldo managed some shots too, and after editing them, if kindly let me show you one here... so stop hurting your eyes and check this:
Scaled Antpitta
Now that's much better.  This photo shows something we noticed in the field... the clay in its bill.  Was it probably looking for earthworms?  Notice the scaled crown and the tawny underparts.  This is a GREAT lifer, specially considering that I did not see it in places where it is supposedly easier (as in Mindo, Ecuador).  What a great day eh?

Quick stop at the salinas

After our successful pelagic trip off Pedasi in the Azuero Peninsula of central Panama, I decided to stay for the night in town with my family.  The next morning, we enjoyed a typical breakfast at the lovely hostal, enjoying the soft calls of the resident White-winged Doves and other common species in the backyard.
White-winged Dove
We planned a relaxed and paused return journey to Panama City.  We did several stops on route, including one at the Agallito beach and the shooping mall in Chitre (Herrera province), where we had lunch.  Then, we did a short visit to the Aguadulce Salinas (saltflats) in Cocle province.  It was already hot (around 1:00 pm), but we knew in advance that the visit would be worth the effort... other two participants of the pelagic trip (Howard and George) visited earlier the place and they texted me the highlights, including a Reddish Egret.
Reddish Egret (immature)
Shortly after entering the saltflats, I spotted a white phase immature Reddish Egret right were it was supposed to be... it was the only heron at the pond, but it was a little bit far away for good photos.  For some reason I was expecting a dark phase bird... so it was a surprise.
Reddish Egret (immature)
The Reddish Egret is a vagrant to Panama; however, it seems to be regular in this site.  By far, the dark phase is more frequently seen... this is only the second white phase bird I have ever seen (the first one was several years ago in this same place).  We continue along the road looking for another species previously found by our friends... a flock with more than 30 Lesser Scaups.
Lesser Scaups in the distance
We did find the ducks... but the flock was smaller... we only counted 18 birds, including at least two drakes.  In the way back, the flock was already gone.  Will this be a good year for migrant ducks in Panama?  So far, many rare species have been reported in central Panama (for example, check this Xenornis report and my own post on Gamboa's ducks).  Apart of these species, we only saw some common shorebirds like Willets, Whimbrels, Western Sandpipers, Short-billed Dowitchers and Black-necked Stilts.  A Caspian Tern at the beach was a highlight too.  Notice the heavy-looking bill and the head pattern showing more black than the Royal Terns.

After some other stops on route, we finally arrived home safely and with several avian highlights in the bag!

Pelagic-mania!

Since in the last pelagic trip off Pedasí we did so well, a group of intrepid birders took to the sea on saturday, November 22nd ... and of course I could not miss this opportunity.  This time, George Angehr (also repeating), Karl & Rosabel Kaufmann, Howard Laidlaw and Darien Montañez joined me at the picturesque town of Pedasí (southern Azuero peninsula in central Panama) the day before.
Sunrise at El Arenal
As the previous trip, the starting point was El Arenal beach, which is less than 5 minutes from the hostal in town where we were staying.  A little "panga" took us to the 30 ft sport fishing boat commanded by Jeff, this time assisted by Elvis (aka Chombo) who took the group photo with my cel phone.  Everything was ready and we started the trip with relatively calm seas, leaving El Arenal and Iguana island behind and heading straight to the deep waters surrounding a seamount at 27 nautical milles SE of Punta Mala.
Howard, Karl, Darien, Jan, Rosabel and George
Apart of some common inshore species, like Laughing Gulls and Royal Terns, a group of dolphins welcomed us spinning in the air.  I don't know the species, but they don't seemed to be the typical Tursiops (Bottlenose Dolphins) to whom I'm used... they were smaller and with longer beaks... probably Spinner Dolphins?
Leaving the ID issues on marine mammals behind, lets back to the birds.  The first pelagic species to showed up was the Galapagos Shearwater... a pair of these flew right by the boat allowing great views.  They were of the pale-underwing form... it is important to mention it since some dark-underwing forms occur and the significance of this difference is unknown.
Galapagos Shearwater
Eventually, we started to detect more and more Wedge-tailed Shearwaters.  Although considered rare, the Wedge-tailed Shearwaters are regular in Panamanian waters.  In fact, this and the Galapagos Shearwaters were the most common encountered shearwaters in all my pelagic trips off Azuero.
Wedge-tailed Shearwater

As usual, most of the birds were pale morphs... and most of them were in heavy wing molt too.  We also saw an intermediate morph.  The slim shape accentuated by its long tail and the underwing pattern eliminates other possibilities... although we were looking for some rarer species that, in Panama, includes Sooty and Christmas Shearwaters!
Wedge-tailed Shearwater intermediate morph
But we were not disappointed at all!  A huge flock of feeding Wedge-tailed Shearwaters (and a lonely Pink-footed Shearwater too), gulls (including my life Sabine's Gull) and terns was patrolled by some feathered bandits specialized in kleptoparasitism... they were harassing smaller birds to stole their catches.  I'm talking about the jaegers... two species in fact.  We saw first a Pomarine Jaeger easily identified thanks to its twisted and elongated central tail feathers (plus other field marks, specially size).
Pomarine Jaeger
Then, we saw a jaeger harassing a Sooty Tern.  Our impression was that this particular jaeger was just slightly bigger than the tern, suspecting that it was a Parasitic Jaeger; however, it was too far away. Later, I photographed an adult jaeger that showed some interest in our boat.  The clean white underparts (with no mottling in the flanks at all), faint breast band and pointed, elongated central tail feathers indicates Parasitic Jaeger.
Parasitic Jaeger
But the surprise came later.  In the distance, another bandit was after a large tern.  This time, the supposed jaeger looked huge, considerably larger than the poor tern and than the Pomarine Jaeger seen before... but more important, this bird had VERY conspicuous and large white panels in the primaries... a South Polar Skua!

Notice the large-bodied appearance and the short, squared tail.  The broad, long wings with those white flashes, the huge size and the powerful wingbeats reminded me a Crested Caracara... yes, a caracara!  Although a marginal photo, this is probably the only photographic evidence of its presence in Panamanian waters (there are several sight records).  I also photographed some other species for my personal collection... including the three regularly recorded storm-petrels in Panamanian waters: Least, Wedge-rumped and Black Storm-Petrels:
Least Storm-Petrel 
Wedge-rumped Storm-Petrel 
Black Storm-Petrel
We didn't see Tahiti Petrels nor Nazca Boobies in this trip... but in return we got several jaegers, skuas and my life Sabine's Gull... that's why I like so much these trips... you can expect the unexpected!

At the highlands with family and warblers!

Taking advantage of one of these long weekends, I went with my extended family to spent some time relaxing in the highland town of Paso Ancho, close to Volcán, in Chiriquí province.  Although not a birding trip, I still enjoyed some resident and migrant warblers that call the highlands their home.  We spent most of the days at a comfortable cabin watching the children playing in the garden, grilling on the barbecue or just chatting.
Gabrielle and her cousins, Ana, Givellis and Kevin
Right at the garden, some common species showed up, including Blue-gray and Flame-colored Tanagers, Yellow-billed Siskins and Rufous-collared Sparrows.  However, I was interested in some common migrant warblers.  The first one spotted was the Wilson's Warbler.
A very bad shot of an adult male Flame-colored Tanager... this bird is well-named!
Adult male Wilson's Warbler
This is the most common warbler wintering in the highlands, found essentially everywhere!  The black cap is characteristic of the adult males... but the bright overall yellow coloration is enough to ID this species.  Then, I spied two other migrant species.  These were working the non-native pine trees next to the property.
Black-throated Green Warbler
Black-and-white Warbler 
As you can see, both the Black-throated Green and the Black-and-white Warblers (both females) were close enough to snap a shot... something quite hard with these restless birds.  We call the latter species the "Creeper Warbler" due to its unique habit of climbing trunks, sometimes upside down, very creeper-like.  The Black-and-white Warbler is very common during the winter through all Panama.  At the other side, the Black-throated Green Warbler is also common during the winter, but only at the highlands; however, it is a frequent passage migrant in the rest of the country.  Both these species are, in fact, more common and widespread than some resident species.  One morning, I went with Gloriela to the Macho de Monte canyon, at the foothills below Volcan... there, we saw one of these resident warblers... the smart Buff-rumped Warbler.

Buff-rumped Warbler
In comparison with the typical and familiar warblers, this species exhibit a different behavior.  It is terrestrial, always found close to water... usually rushing streams, flicking its expressive tail from side to side.  Certainly the Macho de Monte canyon is a great place to find this species... and a nice touristic attraction too!

The Buff-rumped Warbler was not the only river-dweller bird we saw that morning.  A Spotted Sandpiper and a pair of Black Phoebes were present too.  In previous visits we had seen Torrent Tyrannulets and American Dippers as well!

Well, a trip to the highlands is always a nice trip.  Of course, we ended it with the traditional stop at the dessert shop to enjoy some sweet strawberries with cream!
