Bird Walk Sunday, May 9

Please join us this Sunday for a free Bird Walk on the Poro Road. We will meet at 7:30 am down the hill where we leave the cars. As always, we will have binoculars to lend.

Directions: from Las Cruces toward San Vito, take the first unpaved (lastre) road to the right after the hospital. From San Vito toward the hospital, take the unpaved road to the left after Soda La Negra.

The walk will go for about an hour. If we are lucky, we might see a pair of nesting Riverside Wrens or Double-toothed Kites! We don’t have a sign-up link this time — we will be there anyway.

REMINDER: International Migratory Bird Day and a Global Big Day occur the day before, on Saturday, May 8. Don’t forget to bird around your house, along the road or at your favorite spot and submit your list to eBird.

Where We Bird — the Poro Road

Thanks to Julie Girard-Woolley, the SVBC has been birding this hidden road for a few years and found some pretty great birds there. Julie is a ‘walker’ (and an SVBC founder) and this spot is spectacular in March with a huge grove of blooming Poro trees. But we are not there for the trees — so let’s start with a bang: the Riverside Wren.

Endemic to southern Costa Rica and western Panama, Cantorchilus semibadius is one of many very loud wrens

Next up, we have not a migrant but a resident, Rufous-capped Warbler. Although ‘common’ in the northern Pacific, Central Valley and southern Pacific, it’s always a jolt to see that red head, white eyebrow and cocked up tail. Basileuterus rufifrons shares its genus with three other resident Tico warblers.

Here is another photo from Jo who has documented so many species in San Vito from her porch, she is admired far and wide. This is her Smoky-brown Woodpecker — just the head, but that is enough. Who doesn’t love woodpeckers? These are found in the northern half of the Caribbean slope and on the Pacific slope but are ‘uncommon’ in both locations. How did she get this photo? See below for a view you would be lucky to see in the field. Picoides fumigatus shares its genus with the Hairy Woodpecker, the Costa Rican race of which is smaller and darker than those in North America.

By now you will have noticed the photos are all out of synch with the text but it’s hard to resist including all these birds because obviously we are trying to entice you to visit us in San Vito, when you feel safe, and we will be here to welcome you.

One last bird — yes, we saved the best for last — and then the local spot where we go for breakfast when our walk is over. 

The last bird photo is a Double-toothed Kite and we saw two, building a nest, on one of our excursions to the Poro Road. It was pretty exciting! See below for a photo by Randall Jiménez Borbón who works as the Community Outreach Coordinator at the  Asociación Ambiental Finca Cántaros.

Double-toothed Kites often perch in the forest waiting for a troop of monkey to follow. They fly low to pick off any tasty critters the monkeys spook, like lizards and large insects.

See below for another photo we hope will be of interest: the Soda La Negra where we often go for breakfast after a Poro Road bird walk. Highly recommended are the scrambled eggs, rice and beans, sausages, tortillas and the coffee. The interior of this welcoming place is full of plants for sale, too, so you can augment your garden or your porch with some nicely potted flowers after breakfast.

Bird Walk Report: White-ruffed Manakin Lek

This story comes under the category of “Things That Go on While You’re Doing the Laundry” because we know now — thanks to Colleen Nell and Dave Janas — White-ruffed Manakins are dancing in a nearby forest! On Saturday, June 20, Colleen and Dave led us to a mossy log along the Rio Java Trail that these tiny black and white birds have chosen as a ‘lek’ in the OTS Las Cruces forest.

What, actually, is a lek? Well, it’s a little bit like a Single’s Bar but far more enchanting: leks are arenas where males display competitively to entice visiting females to have sex. (Several kinds of birds, including hermit hummingbirds, cock-of-the-rock, grouse, birds of paradise and pihas, as well as some fish, butterflies, moths and orchid bees use leks.)

We were not lucky enough to see the manakins do their thrilling displays but most of us saw them flying around and we saw two predators in the area — likely attracted by the goings-on — a Double-toothed Kite and a Roadside Hawk.

Thanks to the technical know-how of Harry Hull, you can see a short video of a full display from the Cornell Ornithology Lab’s Macaulay Library collection, by clicking here. This opens a video player in a separate tab/window in your browser where you can play the video by clicking on the “go” arrow. (Close that tab/window to return to this post.) In the clip, two males with bulging ruffs compete for the attention of a female. Both males do the “Butterfly Flight” that Colleen described as part of the display and then they dance in step on the log. Finally, as the female waits, both males, one after the other, do a stupendous aerial dive that ends with a flip and a loud mechanical wing flap!

We are grateful to W. Alice Boyle who made this video (and more) in the course of her research on this species in Costa Rica in March 2009. Our guide Colleen worked as a field assistant for Megan Jones at Rara Avis on this very project. Colleen is currently at work on her PhD dissertation at the University of California Irvine. Dave Janas, well known to SVBC bird walk participants, will start working at Las Cruces/Wilson Botanical Garden as the staff horticulturist on July 1.
