African migrant birds - NOT amateur radio

Swift

About now, I start to watch and listen for the returning migrant birds from Africa. Already swallows have been seen in Devon and even in East Anglia, although I have seen none. Last year I saw very few indeed. 

Locally swift numbers did not seem down on normal. Swifts usually arrive here in numbers mid May. Often they are heard screaming in the sky before they are seen. "They are back", goes out the cry and all is still well with the world. Not yet...
