If you love to learn new things, nature will never let you down.

Let’s take crows for instance. Far too many Americans live in ignorance of the fact that these United States are home to more than one crow species. Certainly, anyone reading this post knows all about Fish Crows, especially since Nate wrote about the Frog Crow just this week! I bet most of you can even separate American and Fish Crows by voice, right? I can, yet I had trouble with a crow right outside my office window this weekend. This bird was the size of an American Crow, consorting with an American Crow, and in an area only frequented by American Crows. However, it whined like a Fish Crow.

Have you developed a hypothesis for this puzzling phenomenon yet? Perhaps it’s not so puzzling to you. Just as I surmised, juvenile American Crows sound a lot like Fish Crows, especially when begging for food; Cornell describes the differences in excellent detail. For teaching me something new about birds, the horde of hungry young crows that have beset my block are my best birds of the weekend.

Of course, my unexpected encounter was nowhere near as improbable as the one Corey and tons of other ABA birders had this weekend. Who after all would expect a Gray-hooded Gull to turn up at Coney Island in Brooklyn? Corey dipped not once, but twice in the quest to twitch this gull, but finally made acquaintance with this mega-gull…
