Gardeners are highly attuned to the cycle of the seasons. So are birders.
I woke up earlier this week and thought, "It seems dark for this time of the morning." I had to check my clock to be sure it was my usual wake up time. It was; it's just the days are once again getting shorter. And fall migration season has started.
It seems we just finished talking about spring migration and now we're into fall. And that is true. Spring migration continues into May/June and Fall migration begins in July. The birds are constantly on the move.
The purple martins at Wild Bird Rescue fledged last week; I didn't see any purple martins yesterday while I was working there. I saw postings on OKBIRDS and TEXBIRDS about large martin roosts, which generally precede the birds' departure.
The fall migration is usually more drawn out, so we will have a chance to see birds for several months.
