Birding Slow at the Park

A wet, cool, overcast day at the park kept many birds from showing at my survey stations or the bird blind. Summer Tanagers are now common along the river.
I found a Black-chinned Hummingbird nest at East Park Boundary. It is 20' above the river attached to a straight dead limb of a bald cypress tree. I noted the female last week collecting spider webs from the trees in this area. Today I saw the female again flitting around the cypress trees gathering invisible spider webs. She immediately zipped back to the nest remaining stationary long enough for me to suspect a nest at 150 feet away. Upon closer inspection I was pleasantly surprised. With overcast skies and temperatures around 58 F. this female was off the nest too long to have already laid eggs. I believe she is just finishing the nest, it taking perhaps a week or a few days longer to build.
I waited at nest box #4 to confirm the species nesting in this box. It turned out to be a Black-crested Titmouse, not a Carolina Chickadee. The adult was either feeding young or the other adult inside. Northern Parula continue to sing at various sights along the river.
At the bird blind a single White-throated Sparrow along with several Lincoln's Sparrows still are hanging around. Bird blind hosts say there have not been a great influx of migrating birds at the blinds for the past week. They anticipate new species arriving any day now, especially the buntings and blue grosbeaks.
This past week's rains have caused the Pedernales River to raise to the highest levels I have seen in the two plus years I have been surveying here. Waters were muddy and flowing quite fast. No chance of fording the river anywhere along the park's length. No kingfishers to be found this week. I bet they are having a hard time finding fish in the mirky waters.
