GMT,
Time, and Roost
Using Eagle Transmitter Data to Determine
Roost Locations
Night roosts are some of the most critical habitats to wintering bald eagles, especially in severe winter weather, so we like to isolate those for mapping purposes to look for patterns of regular/annual use, so we can pursue protection of those sites if needed.
The colored column contains data as it looks when it comes from ARGOS. Practice converting GMT to EDT. You figure out if it falls between 18:00 and 6:00 EDT.
