Blue-Grey Gnatcatcher

Polioptila caerulea

These feisty little birds are among our tiniest, much the size of a hummingbird; but their voices (widget-jooo widget-joo joo joo) are among the loudest, high in the oaks in the spring as they court and defend their nests.

For videos of gnatcatchers bringing food to their nest in an oak tree--and to a loudly begging brown-headed cowbird fledgling (which they have been fooled into raising as their own--an example of brood parasitism), please see here.
