To the depths of the Burica peninsula

Due to Panama's topography, there are few sites from where you can launch a pelagic birding trip.  The typical sites (in the Pacific) are extreme eastern Darien province and some sites in the Azuero Peninsula of central Panama.  The logistic is always complicated (and expensive) due to lack of tour operators and pelagic birders as well!  But then, there is another site where the oceanic depths are close to shore: the Burica Peninsula in extreme western Panama.  While looking for good boats to make a pelagic trip, I came upon Hooked On Panama, a fishing lodge at the southerly town of Limones, at the very tip of the peninsula.  They were more than eager to provide boat, crew and chum, plus the on-ground facilities for our pelagic trip after explaining to them the lack of scientific knowledge of the pelagic avifauna in Panama!

This was an scouting trip after all... June - July is probably not the best season for pelagic birding in Panama, but anyway we wanted to make that first contact and to evaluate the feasibility of doing more trips from Limones.   Three other birders joined me: Christian Gernez, Dave Klauber and George Angehr, who is the author of "The Birds of Panama,  A Field Guide" and probably one of the most experienced pelagic birder for Panamanian waters.  Taking advantage of the lodge, I travelled with my family, who enjoyed the pool and the beach while we were out under the sun looking for pelagic birds.  In fact, the excellent road conditions from David city, and the lodge amenities are points in favor.  Another point in favor: the boat!  A locally customized 33' Blackfin vessel with all the safety equipments, spacious, comfortable, designed to offer a 360º view of the surroundings and easily accommodating up to six pax!
Our crew knew exactly what we were up to!  Our captain Chaka took us immediately to deep waters south of Burica island and then to the east along the Continental Shelf break while mate Jacinto helped us with all our needs and with the chumming process (essentially fish guts and pop corn).  They have a lot of experience fishing pelagic billfishes, but this was their first time guiding a group of birders... the essentials tips seems to be the same for both activities (fishing and birding in deep waters).  But even before reaching deep waters, we started to have some nice surprises, like the completely out-of-season Elegant Terns close to the lodge (they are supposed to be breeding in Baja this time of the year) and the Humpback Whales swimming extremely close to the town beach (a little bit early, but not unexpected).  Bird and whale watching could be some activities that the lodge can offer during the low-season months of fishing, as Christian pointed out.

One of the things about doing a pelagic trip in Panama in June-July is weather.  We were always close to dark clouds and storm systems, but somehow we managed to avoid all of them, experiencing no rain at all (OK, Chaka had a lot to do with that).  Still with land at sight, we started to find the first pelagic birds in the form of Storm-Petrels.  With the exception of few Black Storm-Petrels, all of them were Wedge-rumped Storm-Petrels.  Paying attention to this species is key to gain experience on its identification and of other species.  However, after seeing many of them and starting to feel comfortable, we realized that they often showed different flight styles (quite direct with steady wingbeats, but also more bouncing and desperate-looking), size/proportion impressions and molt-timing!  Some birds were fresh-looking while other were in active wing molt... some looked quite small and compact while others looked larger with proportionally long wings...  Were these differences age/sex related, or were they different subspecies?  Or different species?  We need more study on these guys!

The storm-petrels were not the only tubenoses out there, we also find Galapagos Shearwaters and a possible Wedge-tailed Shearwater as well, but was too far away to ID with certainty.  However, the most impressive of them all were the Tahiti Petrels (YES, in plural).  We managed to see up to four different individuals at the same time, sometimes very close to the boat!  Just the fourth record for Panamanian waters, where the species surely is a regular visitor during its non-breeding season.  Thinking on these birds crossing the vast Pacific Ocean to visit our warm waters is simply overwhelming!

Apart of the Elegant Terns seen at shore, we only saw another tern species during the trip: Brown Noddy.  Most of the terns species found in Panama are boreal migrants, so we did not expect to find them in June-July, at least not in considerable numbers.  Our resident tern species (like the noddy) are probably found close to their breeding islands during this time of the year.  Anyway, we enjoyed the sole member of the Sterninae out there... the anti-tern species by the way (dark body, pale crown, wedge tail)

Another highlight of the trip were the Sulids (boobies).  We found three different species (of five possible), including Nazca and Brown Boobies.  At some point, we approached Islas Ladrones that host one of the biggest colonies of Brown Boobies in Panama, crossing several flocks of these boobies flying back and forth from and to the islands.  The Nazcas, as usual, were always far from shore, on floating debris or in powerful flight over the waves showing no interest in the boat.

Soon it was time to go back.  A huge school of Short-beaked  Common Dolphins gave us the farewell before heading back to shore.  Calm waters meant that nobody had sea-sickness at all and the cloudy day help to avoid sunburns!  After a 6-hours trip we were back at the lodge, enjoying a couple of cold drinks and celebrating this very first pelagic experience birding the depths of the Burica Peninsula.  I can not wait to go back!  Would you join me?

Global Big Day 2019! What a day!

And the Global Big Day started!  Last May 4th, thousands of birders around the world joined efforts to record the largest number of birds species in 24 hours.  Of course, new records were set and hundreds of birding histories were told.  You can read the global summary at the eBird page... and my own history here (just keep reading).
Ramiro Duque, Rolando Jordan, Jan Axel Cubilla and Carla Black
Like last year, my intention was to do some pelagic birding... and again, my destination was Bahía Piñas and fabulous Tropic Star Lodge in eastern Darien.   Last year, getting to Bahía Piñas was a complete adventure... this year, well, there were some inconvenients as well.  First of all, I was not able to take the commercial flight to Bahía Piñas... all the seats were booked due to the Presidential Elections that would be held the next day.  However, the NGO ADOPTA Panama Rainforest managed the support of the government (through MiAmbiente) who contributed with transport and logistics for several teams to remote counting areas, including the ADOPTA Team to Puerto Obaldia, in extreme eastern Guna Yala.  Guido Berguido (ADOPTA's executive director and a friend of mine) included a stop in Piñas in the flight plan, so I joined them in the ride.  After some mechanical setbacks, we were finally in the air heading to Piñas.... but due to some logistical problems, the ADOPTA team had to stay in Piñas, so we improvised a little bit.  Rolando came with me on the boat while the rest of the team birded around the town and the airstrip.

After an early breakfast on May 4th, I was ready for the pelagic trip.  Rolando was already waiting for me at the dock, as well as the crew of our fishing boat.  The day was dark and soon it started to rain... a lot!  Anyway, we headed directly to deep waters.  The Continental Shelf break is very close to the coast in this part of Panama, meaning that quite soon we were enjoying pelagic birds around us.  These waters are incredibly rich, the avifauna is abundant and easy to approach, paralleling the other wildlife for what these waters are famous: pelagic fishes, specially billfishes!
We were not there to fish, that was for sure... we were quite busy counting and identifying the birds around, specially the storm-petrels.  Three different species (Least, Wedge-rumped and Black Storm-Petrels) swarmed around the boat in huge numbers!  Check one of the flocks that we crossed containing all three species.

We scanned these flocks looking for rarer or unreported species for Panama, and I tried to took as many photos I could... sometimes you detect rarities on land, reviewing the photos, but not this time.  Apart of the storm-petrels, we saw both Galapagos and Wedge-tailed Shearwaters, several terns and boobies species, including obliging Nazca Boobies!  We essentially followed a route along the shelf, stopping at usual fishing hotspots and whenever we find activity, both of birds and other animals like dolphins and tuna.  In fact, a huge school of tuna was followed by more than 100 Short-beaked Common Dolphins!  What a sight!

Time flies when you are having fun, and soon it was time to head back to the lodge.  Closer to the coastline we find different species, like Brown Pelicans and Blue-footed Boobies, adding them to the growing list.  It was not an exceptionally long list, but certainly one with quality birds.  In fact, we were sure that we got that day several unique species for the country, since we were the only team birding the seas.

Back at dock, I said good bye to Rolando, who went back to Piñas town to bird with the rest of the group.  After few minutes of rest, I also started to scan the surroundings.  The lodge is surrounded by lush forest, and some good species wander around.  Unfortunately, I was not able to relocate the Viridian Dacnis I saw the day before, but anyway, I kept birding.  The highlight was a flock of swifts including Spot-fronted Swifts and a lonely Chapman's Swift!  Creepy photos of both them at this eBird checklist https://ebird.org/camerica/view/checklist/S55817569.  At night, I ended my participation recording Gray-cowled Wood-Rail and Mottled Owl... but a Crab-eating Fox just in front of my cabin stole the show!

I ended up submitting 72 species for the day, a modest number compared to other teams... but for second year in a row I manage the greatest number of unique species to the national total, only matched by Isaac Pizarro (who birded all the down from Pirre range to the lowlands around El Real): both recorded 11 unique species.  These numbers reflect that we need more participation... another team doing pelagic or more teams covering Darien National Park; but also, they indicate how important each participant is.  As they says, every bird counts!  Panama numbers, as in general, were good.  We didn't break our previous year record of 750 birds species since we got 731!  Still an awesome effort that positioned us as first for the Central American region and 8th worldwide!  I wish to thanks all the participants who kindly donated their time and effort in making this possible, and to ADOPTA a Guido Berguido for coordinating the logistics and transportation provided by the government.  Next year I hope more participation and official support to keep making Panama number ONE in Central America in terms of avian diversity!
