It’s been an unusual year on two counts in south Texas this winter: there have been a lot of unusual bird and there has been a lot of unusual weather. The local birders are beginning to ask if the two are related. The weather has seen one cold front after another drop into southern Texas. We get one or two decent days and then it’s another cold front. Today, I’m sitting here writing this in my shorts, because it’s 27 degrees Celsius outside. But the forecast high for tomorrow is 12 degrees. And so it’s been all winter. The cold has been extending into Mexico as well, and that’s been the source of many of the rare birds that have been showing up here. Two species, the Bare-throated Tiger-Heron and the Amazon Kingfisher, have never before been seen north of the Mexican border.
