Three nights a month research staff and citizen scientists keep tabs on shark movements in the Reserve, and last week's excursion could not have been better. In addition to enjoying a balmy March evening with a marvelous sunset, the crew captured three bonnethead sharks, one lemon shark, and a cow-nosed ray, and NO MOSQUITOES!

Reserve staff and Team OCEAN volunteers posted a small portion of beach on the south tip of Keewaydin Island and in early April will post part of an emergent sandbar at Cape Romano Shoals. These areas have been posted annually from early April until late August to protect nesting habitat for least terns, black skimmers and Wilson's plover since 2001. They installed informational signs connected by string and flagging to clearly mark closed areas. Two marked crossover trails on the south tip of Keewaydin Island lead beachgoers across the island to access the Gulf-side beach.
Greg Curry, Rookery Bay Reserve's Resource Management Specialist, returns to document the re-growth progress following the final prescribed burn of the season, two weeks ago. Already, there are signs of new plants sprouting, old plants re-sprouting, and visible wildlife activity in the area.

Jill and Beverly on the research staff braved red tide and being chased by a big dog to map the shoreline along the south end of Keewaydin Island. Jill will be going back out to finish mapping the north end to complete the entire shoreline. In addition, Bev also mapped several areas at the south tip to guide the bird posting this spring. The southern tip has accreted ¼ mile since the project started in 1998! The island is eroding in other areas.
Rookery Bay staff and volunteers spotted two razorbills along the shore of Keewaydin Island while conducting the bi-weekly bird census. Razorbills are a North Atlantic species related to puffins and, more distantly, penguins. There have been only 14 previous records in Florida but since early December researchers estimate more than 1,000 of these birds have been seen statewide. Razorbills have also been seen locally at the Naples Pier and along Marco Island. Reserve staff also encountered a razorbill carcass that had washed ashore and provided it to researchers for further study.
Scientists and birders have offered many theories as to why razorbills are showing up here at all, let alone in such large numbers, however it will take time for all factors to be considered before any sound explanation can be reached.
