Took a break from work this morning (Tuesday May 29) at 0800 and ran over to the USTP to see if the avocets were still there. It only took a few seconds of scoping to find the two AMERICAN AVOCETS reported on the 26th (thanks Chuck). Also present were a flock of seven WHITE-FACED IBIS. Both species were on the north pond. The avocets were fairly cooperative so I attempted to photograph them. When I finished photographing the avocets, the ibis (ibises?) were gone. I never heard or saw them leave so I don't know which direction the flew. However the mudflats are fairly extensive so they might return. The avocets were still in place when I left at 0845.
