So sorry, Cher! Such a bummer! Think it was a snake? What an amazing photo you have of those Robins hatching. That is amazing!
Funny story- when my first bluebird nesting was going on, so was the robin’s. Was so funny to see the robin parents fit about ten mealworms in their beaks at a time to feed nestlings. Now, one of the juvenile robins stands guard on my feeder for hours (even when all mealworms are gone). That little thing that has only been in the world for a short time is bullying all the other birds away from feeder. Little stinker!
Had to get a new caged feeder for bluebirds.
Hope you get better luck for rest of season!
