Hi, Saturday (May 16) was sort of slow, around the Visitors Center at Rock Creek Park, Washington, DC. There were several species of warblers singing and seen. SWAINSON'S THRUSH and a nice male ROSE-BREASTED GROSBEAK were among these birds. Other birds included: RED-BREASTED MERGANSER-8 flying over, heading north. The birds appeared to be females and immature males. They weren't that high above the tree tops. RED CROSSBILL-6, flying at tree top level at the open area around picnic area number 14. I happened to be looking in the right direction as these birds flew northeasterly, calling. Sunday, May 17, was slower still for warblers. I heard a CANADA WARBLER sing three times as I got out of the car, but as soon as I pished, it fell silent. Other birds included: COMMON or FORSTER'S TERN-6 flying over, heading north. They too were not that far above the trees. SOLITARY SANDPIPER-3, following the terns about a minute later. Rob Hilton robert@csa.com Bethesda, Md.
