[cobirds] Turkey Vulture FOS - Masonville roost, Larimer County

Hi all,

   Seems we are right on schedule. Easter weekend the first Turkey Vulture "scout" arrives single at the Masonville roost. Arrived this weekend - one bird. For many years Alex Cringan and I shared numbers comparing the roost at Mountain Ave in Fort Collins and the Masonville roost. Invariably they arrived first in FC, then showed up here about a week later. His theory was that the Mountain roost was the arrival spot and then birds would move out to outlying roosts. We were never able to confirm that, but it was always about a week's difference between the two roost arrivals.

   Past dates of FOS in Masonville:

2005: 3/24

Happy spring!
