Next to me was a copy of “Birds of Central America” with a somewhat longish subtitle “Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama” by Vallely and Dyer from 2018. In a way, “Birds of Central America” was the prequel of this new edition.

Whatever the reason for getting involved with this massive day of birding, every GBD has been a success where literally thousands of species are found by thousands of birders. I have been able to do that in Costa Rica because literally hundreds of bird species can be accessed in a question of hours.

I like observing them, reading about them, grappling with species and subspecies identification, and even—on a good day—talking about sparrow taxonomy. Peterson Reference Guide to Sparrows of North America covers 61 species of the New World sparrow family Passerellidae that breed in Canada, the United States, and northern Mexico.

I want to alert you to a recent study (from April) that looks at the plight of bird populations under conditions of climate change in Europe and North America. From the Abstract and summary: Changes in climate can cause populations of species to decline, to increase, or to remain steady. Stephens et al. Let’s look at that first.

Here at 10,000 Birds we are going to dedicate the coming week, from today until Saturday, to invasive species. Of course, most of the species we will cover will fit the more traditional definition of invasive species, which usually only covers introduced species that are doing harm to species in the areas to which they are introduced.

Perhaps our outrage at invasive species can be a bit hypocritical at times. Listers are quick to put aside their condemnation of invasive species once they attain that coveted status of exotic: not native, not fully naturalized, but established well enough to be countable by the prevailing authority. That’s where we come in.

Towhees are large, ground-hugging sparrows that occur only in North America. The first was strange only on a personal level, as I had never before seen a juvenile of the species. They belong to either the Pipilo or Melozone genera, or perhaps both, as their taxonomy is still a point of contention.
