The White Throated Sparrows must have migrated in last night during the storm, as there were many of them for the first time at the feeders.
The yellow and white markings on the head are bolder on some than on others, as you can see in the pictures.
We should be catching lots of these at the bird banding activity at Springbrook tomorrow morning, along with many other migrants. It starts at 6:30 AM for any who want to join us, and goes until about 12:30, if you don't want to rise so early. All are welcome.
White Crowned Sparrows are one of the most attractive sparrows we have. They are often mixed in with the White Throats, but the difference is easy to spot. The black and white head, no yellow, and the gray breast and throat. Also notice the more pinkish (so the book calls it) colored bill instead of the more blackish bill of the White throats.
I only had a few minutes today, but took these pictures just after the rain stopped
