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.
