All about timing!

At this point, most of you know that I'm doing a Big Year in Panama.  As in any other place, making a big year implies a lot of time and, why not, money (to travel, essentially)!  However, if you have a profound knowledge of your area birds and their natural history (or get advised by the people who has that knowledge), you may save both time and money... specially if you have a regular job that doesn't implies birding or if you are NOT taking a sabbatic year to birdwatch!

It is all about timing... knowing when some species are most likely to be more conspicuous than usual, when is their peak migration, or when they visit more accesible sites so you don't have to organize a whole expedition to look after them.  A have many examples of how good timing helped me to find rare or unusual species... but I'll write about two recent experiences in this post.  It took me only two days to trackle down two VERY localized species for Panama, both of them represented by endemic forms that, coincidentally, are named eisenmanni, honoring Eugene Eisenmann (1906-1981), a Panamanian ornithologist well-known in the neotropics by his nomenclature arrangements.  The first one was Grassland Yellow-Finch (Sicalis luteola eisenmanni).  As many other grasslands species, this one is declining in our country due to habitat loss.  Even knowing its usual haunts, it is not easy to find this species in Panama... except during its breeding season when adult males are conspicuously singing atop low bushes in the middle of pasture land.

Not only that... this species is absent from apparently suitable habitat, even at the SAME location where we use to spot it... El Chirú, Coclé province in central Panama.  These males are not easy to find either.  The very high-pitched song is hard to follow to the source, there are only few territories (and individuals), you need to crawl under barbed wire fences and dodge curious cattle and being expose to ticks and chiggers while trying to approach them (because if you don't lie down they will spot you right away in their preferred open habitat).  All of these is worth the effort... after just 1.5 hours of driving from Panama City to El Chirú, I was able to find this adult male right away.  Try to do the same any other month... you'll spend weeks around without finding even one!

I enjoyed this male for some minutes until it flew after another adult male.  Then, I left the place and headed southwest, to western Azuero Peninsula in central Panamá. The several stops along the way (to birdwatch, of course) made a 2.5-hours drive from El Chirú to the town of Malena into a 6+ hours trip.  At Malena, I joined my friend Kees and his wife Loes, who run the lovely Heliconia B&B, my home for that night.  During dinner, we planned the next day: an early breakfast before the 1.5-hours drive to the town of Flores, in extreme southern western Azuero peninsula.  Why?  Well, nances and figs.  Yes, fruits!  Our target there inhabits the middle elevations forests of the Cerro Hoya massif,  essentially inaccessible without mounting an expedition or without an strenuous hike (probably more accesible through Río Pavo).

However, during the few weeks when the nances and figs are ripe, our target descend from the mountain to feed on them at the border of the forest with cattle pastures.  And we knew a place where that happens regularly: Finca Velásquez.  Since many years now, Juan Velásquez and his lovely family have been watching and reporting the returning of the Azuero Parakeets (Pyrrhura picta eisenmanni) to their property bordering Cerro Hoya National Park.  Over the years, the ripening of the fruit has been more difficult to predict and the flocks that descend are smaller, shyer and stay for shorter time... so the Velásquez family's input is VERY important to travel there and see the parakeets!

Juan waited for us at the entrance of the finca at 7:00 am and guided us through dirt roads to his property. As soon as we got there it was evident that the fruiting trees were attracting birds, including some parakeets and parrots species, but not the Azueros... yet.  Juan invited us to wander around since he usually sees the parakeets around 9:00 to 10:00 am and pointed us the preferred nance trees. Even before we were able to do so, a flock of resident Great Green Macaws revealed its presence with raucous calls while they flew above us to sit on a fig tree by Juan's house.  It is amazing how such huge birds "dissapeared" as soon as they perched on the fig tree!  We then took the trail to Río Pavo, finding nice activity of mixed flocks, including some western Pacific lowlands specialties like Orange-collared Manakin and Black-hooded Antshrike.  The raptors were represented by some nice species, including rare Black-and-White Hawk-Eagles and obliging White Hawk that posed for photos.

At 9:00 am, we were waiting in front of the nance trees pointed before by Juan.  On time, a flock of 12 Azuero Parakeets flew in and perched quietly in one of the trees!  We had excellent views while the birds were eating, but they did not allow photos.  They stayed less than ten minutes and flew away.  One hour later, the same flock arrived again and did the same.  This time I managed to obtain poor photos of an individual feeding on nance.  The Azuero Parakeet is considered part of the Painted Parakeet complex of South America; however, its extraordinaire isolation and differences in plumages respect to other forms merits it specific status according to some authorities, including the Panama Audubon Society.

Without the opportune help of the Velásquez family, it would be impossible to see this species and to be back in Panama City by dinner time!  So, there were no need of expeditions nor days off at work (I already runned out of permits for this year)!  There is no doubt that good timing is everything when birding!
