I drove around the area some hoping maybe the Collared Plover had relocated somewhere nearby but I couldn't find any water. There is a nice wet spot with shorebirds to the east of Hargill on FM 490 but no small plovers were present. So I ran over to the pond on FM 1015 on the east side of Delta Lake. Here I found a couple of Black Skimmers which were Hidalgo County year birds for me. Here's a digiscope shot from about 80 yards.
At this point the wind was howling and blowing lots of dirt, but I thought I should checkout the Sugar House Pond. I parked along FM 1425 and walked up near the northeast corner on the pond. Wow! What a lot of birds!
I estimated the number of Wilson's Phalaropes at 2500 and didn't really try to get numbers for anything else as I could hardly stand on the dike because of the intense wind. I shall return.
