|immature Yellow-throated Warbler|
Since most of the entire spring passed with very little birding I headed out early this morning. There was fog at the river early but it burned off fairly quickly.
The area I visited is a rich environment for Yellow-throated Warblers. The feeding frenzy began early. This year's fledglings begged and squabbled with each other for the parents attention. Most trailed behind the adult bird and made some attempts at searching for insects.
My attention became focused on one particular adult that hunted with a sense of urgency beyond that of the other adults.
After several minutes of watching it fly off then come back I realized why. The poor little warbler was trying to feed the insatiable appetite of a bird several times its size.
Regardless of how many insects the warbler brought to the young Cow Bird, every time the warbler flew off, the young bird was still begging for more.
