Today after work I visited Centennial Park in Howard County, birding the lower 
part of the lake. Despite the cloudy, raw weather birds were active. Lots of 
Tree and Rough-winged Swallows were flying over the water. Two Ospreys 
were seen and a whistling call attracted my attention to a soaring adult Bald 
Eagle. I saw one Caspian Tern and five graceful Bonaparte's Gulls including one 
with a full hood and a slight pink tinge on its underparts. A Barred Owl called 
from the woods near the dam. There were maybe a dozen each of yellow Palm 
and Yellow-rumped Warblers and a few Pine Warblers that added color to the 
gray day.
