After three truly exciting and productive weeks of hummingbird field work in Costa Rica and a fourth week making presentations in Washington, DC, I'm finally back home in York, South Carolina working through our data and photos. The 22 January-1 February 2008 installment of "This Week at Hilton Pond" summarizes our Week One results and includes a ton of photos of hummers, non-hummingbirds, and other flora and fauna, people and places. |
