Birders and photographers: please come to a Hummingbird Workshop at Lydia Vogt’s property, Finca Sofia, at 8:00 am this Sunday (Oct. 4)!

You will find this beautiful and “birdy” property on the road to Los Angeles, just past the large AyA water tank on the left. The gate will be open a little before 8:00 am and you will see the sign for “Finca Sofia”. Park inside the gate; please bring something to sit on plus a hat or sunscreen.

We will spend an hour or so sitting by the “Pavo” and “Rabo de Gato” bushes watching and identifying hummingbirds feeding on and guarding these food sources. Last week on our bird walk there we had 8 species of hummingbirds in as many minutes!

As usual, we will have binoculars and bird books to share. This will be a good opportunity to learn these beautiful but difficult-to-identify birds!

Pajareros y fotógrafos, ¡por favor únansenos en un Taller sobre Colibríes en la propiedad de Lydia Vogt, Finca Sofia, este domingo (4 de octubre) a las 8 am!

Encontrarán esta hermosa y “pajarera” propiedad en la carretera a Los Ángeles, después de pasar el tanque grande de agua del AyA a la izquierda. El portón estará abierto poco antes de las 8:00 am y usted verá el letrero de “Finca Sofia”. Parquéese dentro del portón; por favor traiga algo sobre lo cual sentarse y un sombrero obloqueador solar.

Vamos a pasar más o menos una hora sentados junto a los arbustos de “Pavo” y “Rabo de Gato” viendo e identificando colibríes alimentándose y resguardando estas fuentes de alimento. La semana pasada, en nuestra caminata para pajarear allí, ¡vimos 8 especies de colibríes en la misma cantidad de minutos!

Como siempre, tendremos binoculares y guías de campo para compartir. ¡Ésta será una buena oportunidad para aprender sobre estos pájaros hermosos pero difíciles de identificar!

Bird Walk Report: White-ruffed Manakin Lek

Looking for manakins. Photo by Harry Hull.

Looking for manakins. Photo by Harry Hull.

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.
