Saw something interesting in Spain. We heard a lot of alarm calls from sparrows and goldfinches that were nesting in the villa garden and we saw it was because a kestrel was circling and then landed on a tree.
As we were watching, the kestrel flew up under the eaves of a neighbouring apartment block and clung with wings open, to a house martins nest trying to reach the babies. It couldn't cling on for long, nor could it reach into the nest and had to fly off.
It returned again the next day and once again, we were alerted by the alarm calls of all the nesting birds as it circled overhead.
We mentioned it to a birdwatching friend who said he had never heard of a kestrel clinging to a nest like that.
