some of the warm weather birds are showing up at the forsythe refuge. I am surprised as it is still chilly and a chance of snow on Sunday
Temperature is not always the determining factor. ; Length of day and biological ones also play a part. ;
temps are still a big part of it as they affect the food sources for birds so they move to warmer climates for food sources such as fish or insects and yes time of day and breeding also play a part in it
