I counted as many as 30 Black-bellied Plovers over Patton Turf Farm this 
morning. All were seen flying in flocks of 17, 2, and 11. None were seen 
on the ground. A big number for Montgomery. No other shorebirds seen 
except for a killdeer despite numerous puddles from last night's heavy rain.

Wish I had time to check Summit Hall TF but with all the rain would 
probably have required a swim across the canal to NPS/turf farm property 
line to get a decent look past the foliage. The focus wheel on my Nikons 
has not worked right since trying this about 2 weeks ago.

Good birding,
