Over the last few years, I have observed some species apparently "disoriented" by the very hot and dry autumns in central Italy. In particular golden eagles in courtship or very territorial flights and corvids species bringing twigs to used nests (or new nesting sites). Do you have any studies you can tell me about similar behaviors? The causes? Some believe it is due to "false estrus", or the hormonal response that autumn temperatures similar to spring temperatures could cause. What do you think about this?
