We have a nest with finches on a ledge under the eaves. When you climb on the garden bench you can see the young birds’ enormous gaping beaks squealing for food. The parents are flying to and fro to forage. The cat has also spotted the nest. She climbed on the bench, but she can’t get any higher.
The parents have discovered the danger. Mom is sitting in the gutter and tweetering to dad who is in the next tree. The young ones keep quiet. Then mom flies further into the same tree, still making seductive noises. It works: the cat has moved away from the nest. She is now chasing a bee.
After a while the parents resume their task and all is well.
