funny bird names

Some bird names are completely understandable, based on their coloration (e.g., Black-capped Chickadee or Gray Jay) or some attribute of their exterior anatomy (e.g, Tufted Titmouse, or Spot-winged Grosbeak), or a particular behavior or association with another animal (e.g., Cattle Egret), or even where they are most commonly found (Boreal Chickadee or Carolina Wren).   But some birds have nonsensical names that make you want to look up how their name originated.  Such a bird is the Evening Grosbeak.  Why evening?

This photo is so dark and dreary it might have been shot in the evening, but it is actually mid-day at foggy, cloudy Sax-Zim bog.  Wouldn’t a more appropriate name for this bird have been White-winged Grosbeak? Unfortunately, there is already an asian finch of the same name.

A little research confirms that the bird got its name from the mistaken impression that it “sang” in the evening.  “Sang” in quotes because the bird doesn’t really sing but emits a series of one-note chirps, burbles, and burps at all times of the day. So…my suggestion is it be renamed the “black-capped, yellow-browed, black and white-winged Grosbeak” (and that should take care of identifying it).

Evening Grosbeak male and female

Like other finches, male and female Evening Grosbeaks have distinct plumage differences. For description of what constitutes “finchiness”, see my post on Finch vs Sparrow

Evening Grosbeaks and Pine Grosbeaks (which we also saw on this trip north) are members of the Finch family, although several other Grosbeak species (e.g, the familiar Rose-breasted Grosbeak we see in the spring and summer) are members of the Cardinal family.

Chow time at the sunflower feeder.  The female lacks the golden yellow colors of the male.

Their big crushing bill is quite useful for cracking the large seeds that smaller finches like Pine Siskins and Goldfinches cannot manage. Typically, Evening Grosbeaks eat seeds in the winter but switch diets to become highly insectivorous in spring and summer. This implies that their gut anatomy and physiology makes some marked seasonal shifts as well.

Although their winter range covers much of the U.S., these birds usually hang out in coniferous forests when not visiting bird feeders, and they prefer to nest in spruce forests at northern latitudes or high altitude.  That probably explains why I haven’t seen them in my backyard.
