New information indicates that Snake Key, in addition to all the other birds now roosting there, is a significant pre-migratory mass roosting site for Purple Martins. Folks in Cedar Key started seeing and reporting massive numbers of purple martins a couple years ago in the mid to late summer. The Refuge staff members worked with Dr. Jason Fletcher, a Disney Animal Kingdom researcher who tagged some of the birds. One was tracked to Snake Key after last breeding season. Further investigation by Dr. Fisher and Refuge biologist Vic Doig show that as many as 5,000 Purple Martins were roosting overnight at Snake Key in July.
