Yesterday's storm birding results were quite unprecedented for modern times. Although I was unable to find any "mega" rarities, the cumulative diversity and totals of several coastal species were remarkable. I sat on the Falcon Lake Dam for over 4 hours mid-morning to early afternoon and while I racked up an impressive checklist, I failed to locate any true seabirds. More on that in a separate post.
After a brief dawn visit -- that was rather unexciting -- I returned to Lake Casa Blanca in Laredo late afternoon and hit the jackpot, with apparent first county records of Magnificent Frigatebird (7+), Black Skimmer (6) and Royal Tern. Also, at least 3 Common Terns which are rarely reported in the county and a very rare-in-July Ring-billed Gull.
What did others find yesterday?
