A continuation of my previous post on bird feather anatomy - a close up of their heads. Which, incidentally, is very important when identifying birds, especially sparrows. Sometimes, immature birds look similar to adults of a separate species, but a good, hard look at their head patterns can explain the difference. Most of these names are pretty simple when you think about it, but there really are a lot of them.
The bird on the bottom is a White-Throated Sparrow. While the white throat is pretty obvious here, it’s often hard to spot in the field, so one key marking is the yellow patch on the fore-supercilium, between the eye and bill.
