I know this isn't about chickens but I need some help. I am a huge bird lover and every year I take time to locate nests and I watch as they are built and the eggs are laid. I always keep my distance from the nest so I don't attract attention, but the last few years none of the nests have been surviving. Every single nest close to the ground, except wren and mockingbird nests, gets raided. The wrens are very sneaky and even I can't find them and the mockingbirds attack everything that comes near their nests. So far I have lost a mother cardinal and her two babies, another mother cardinal and her three eggs, and just last night I lost a mother song sparrow along with her beautiful nest of five babies who just opened their eyes and got all of their feathers in. Right now I have one more cardinal nest that is fairly exposed and has two eggs being incubated that I want to save, and I think it is my neighbors cat who is to blame for the deaths, She is an outdoor cat who has broken into my screened in porch at night before and who I constantly see sneaking around my yard. She roams the neighborhood even though that is against our HOA rules and I have seen her pouncing at birds before, but never raiding a nest. Any ideas as to whether the killer is her or not or how I can protect my nests? Please help!
