Magnificent Riflebird: Fluid Coordination | Cornell / National Geographic

November 16, 2018

The display of the Magnificent Riflebird shows how important minute details can be. The male abruptly fans one wing and then the next, using footwork to keep the female directly in front of him, where he can control what she sees. Interestingly, females may participate as well. Eventually the performance subsides into a nearly motionless pose as the male waits for the female’s decision. Filmed and photographed by Tim Laman, Ed Scholes, Eric Liner and Benjamin Clock.

There are currently seventy-two short films in the entire Birds-of-Paradise Project playlist, ranging from 26 seconds to 8:29. In the upcoming weeks, we will present some of our favorites.

Why do we cry? It’s weird. Humans leak water out of their faces when they get sad. Are we the only animals that do this? What does it mean? What is it for? Here’s the science of human tears!

Three-way-hybrid American Wood Warbler Found in Pennsylvania

November 10, 2018

Please note that this is not an April Fool’s Day report.

I’ll say only than the hybrid’s mother seems to be a “Brewsters” Warbler, which is itself a hybrid between Blue-winged (Vermivora cyanoptera) and Golden-winged (Vermivora chrysoptera) Warblers. The father is a third species of warbler. Get out your field guide and read the fascinating article, including many photos, by GrrlScientist.

Ballona Freshwater Marsh: 3 November, 2018

Did you know or did you remember that years ago what is now the Freshwater Marsh was a weedy field and a center of contention among land owners in Playa del Vista, developers and advocates of the Ballona Wetlands?

It was completed as the Freshwater Marsh in February of 2003 and wow! Look at it now!

Our annual “stroll” around the marsh in lovely sunny weather was marked by seeing 47 different species – a far bigger number than seen in 2002.

The default birds were the usual American Coots and the Audubon’s Yellow-rumped Warbler (which has a conservation status of “least concern” = population increasing).

The group was quite interactive – everyone found something wonderful to show to the rest of us. One highlight was a Virginia Rail skulking in the reeds.

Another was a selection of Kingbirds – the expected Cassin’s and Western and a Tropical! There were discussions about a Yellowlegs (Greater or Lesser) and Dowitchers (Short-billed or Long-billed) – which and why.
