I saw a crow steal an egg from a mockingbird nest today. Made me think...Just a tip for beginner landlords, for next season.. If you have a Martin house with standard 6x6 compartments, if you haven’t already done so, it’s advisable to modify them to 6x12, and use SREH. The martins will always nest in the farthest back section, making it virtually impossible for predatory birds to reach in and grab them. Of course you still need pole guard protection for land predators. Your martins will be much happier, and so will you!
Good luck to all,
Rob

Brave crow! Good advice, a 6x6 round hole is an invitation. Thanks!

Someone posted a picture here a few years ago of a starling flying away from a Martin house with a PM baby (pinkie) in it's beak an dropped it 100 feet or so from the colony. I have also seen pictures of crows raiding bird nests too. It is well known in the waterfowling world that crows devastate duck nests, eating the duck eggs.

Rob,

Good idea to protect your martins before you have a problem. At our former home, we attached wooden nesting shelves for doves under the eaves of our home. The doves raised many babies for many years until a crow found them. The crow would eat the eggs and come back for the second attempt eggs also. They also did the same to Robin nests.

Crows are smart and are capable of communicating with each other. We never had another dove nest raise babies as the crows would return each year. Don't let the crows get even a single martin egg. Thanks for caring for your martins. Gary

Those mocking bird parents chased that crow all over the place, but he never did drop that egg.
