I was out this evening and around 7:00 PM many purple martins came flying through. Some made passes over head above the gourd rack. Hope they were scoping my set up out for a return trip next year. At first I saw maybe 3. Then 6. Then 10. They were flying every which way over my set up and yard. They were 25 to 30 feet high. I expect maybe 50 or so flew southward tonight. I seen many of them flying even up to 7:30. I came in around 7:45 and there were still 2 or 3 flying towards the South yet. Not sure were they will rest for the night. Must be migration from the Northern States and Canada.

- Martin Colony History: Erected 1st house in 1997. Birds were checking it out before Mike got down from the ladder. Six cavities had a little colony 1st year. Grown to 88 cavities all gourds with near 100% occupancy. Most important factor for success is rain = bugs.
Yes, Steve, there is a lot of migration going on this time of year. I checked the radar for activity in your area. I couldn't see a roost in your area, but there are quite a few south of you. So, I'm sure you were seeing Purple Martins heading for a premigratory roost.
At what point does a "pre"migratory roost become a "migratory" roost. Is there even such a thing as a "migratory" roost? Migrating birds must stop to rest and feed along the way. We know they move pretty fast once they begin migrating. But, they have to pause for resting. With the Purple Martin the feeding can be accomplished on the move -- but, the resting -- I don't know -- can they fly and sleep at the same time -- NO -- they have to stop to rest.

Laverne,
How do you check the radar to find roosts?
