What to Expect When You’re Expecting

NestWatcher Loyd Marshall kindly shared with us a helpfulĀ photo collage that shows the growth progression of Prothonotary Warbler nestlings. If you have nest boxes installed for this species, feel free to check it out and save the image to your computer to help with your nest monitoring. Thank you, Loyd, for sharing with us!
