So, when you're talking about a bird called the Nashville Warbler, you would think that the bird would have some close affiliation with that city, or at least a strange liking of country music. Well, it turns out that the bird got its name where a famous ornithologist first saw it. The truth is that this cool little bird can be found over a fairly large swath of the country. In fact, there are two distinct groups of the Nashville Warbler. One breeds in the northeast, while the other breeds in the northwest. Both populations spend their winters in southern Mexico. The bird both breeds in California and passes through on its way north, and we've been seeing a lot of them lately. Check out the maps below for more details:

At the end of March, we were seeing a lot more of them:
Now here we are at today's map -- numbers still growing:
