Texas Coast Warbler Count

Going birding? April 17th is the highest warbler count for High Island

November 18, 2022
I recently pulled the eBird dataset into postgresql and decided to look at which day of the year has the most recorded species in Parulidae. Its April 17th. This is for Chambers and Galveston counties that include Anahuac, the Bolivar, and Galveston Island. It turns out calculating warblers-per-minute effort is useless without doing rarefaction. The vast number of lists in April along the coast wash out any signal as you run out of warblers to see pretty quickly.

Erik Iverson and Brian Sedio have kicked of the Texas Tropical Network. I'm looking forward to it.
Green Jay

Green Jay western range limit

February 15, 2022
I recently banded two Green Jays in Del Rio, TX, which is the absolute western range limit. Beyond Del Rio, the habitat is mostly Chihuahuan desert and not suitable for the species. We'll have to see if they continue alogn the Rio Grande to the Big Bend area.

Postdoctoral Scholar – Climate change research

October 12, 2021

The Keitt Lab[1] at The University of Texas at Austin seeks a postdoctoral scholar to join our team. With funding through UT’s Bridging Barriers program[2], we are investigating how climate and landscape change is affecting the biogeography of species and communities across Texas and beyond.  Candidates with particular interests in geospatial analysis, environmental sensing, biodiversity conservation, and ecosystem services are particularly
