Breeding Birds Mob Screech Owl

Today I had a picture perfect view of all the current bird life residing at station #4 - Trammel Crossing. Earlier in April I heard a Eastern Screech Owl whistling along Twin Falls Creek. Today that owl caused quite a ruckus among resident birds. I walked upon a mixed flock of birds mobbing the owl. Two Black & White Warblers, White-eyed and Yellow-throated Vireos, Carolina Wrens and Chickadees, Northern Cardinal and a Yellow-billed Cuckoo. The owl eyed me for a few minutes then decided to split the scene escaping the flock of scolding birds.
Birds were singing at all my stations, including a late Least Flycatcher at Tobacco Creek. This bird was heard and seen at this location two weeks ago. It will not find a mate in this part of the country as its nesting range comprises deciduous forests around the Great Lakes and Midwest.
I was surprised to find two Green Kingfishers flying by at the Tobacco Creek confluence to the the Pedernales River, first sitings of the year. At the Tobacco Creek Seep an adult Louisiana Waterthrush was still bringing food to its nest nineteen days after I first discovered the nest. It carried away fecal sacs from the nest.
The day was too hot and muggy for me to spend any time at the bird blind today. When I do finally have time to visit the blind it is the worst time of day 12 noon. The best time to visit the blinds are right after sunup.
