Swallows on the foreshore in Napier - take 1

There are a huge number of Welcome Swallows flitting around the foreshore at Napier, NZ. You have to look hard to see them, they are so fast and change direction so quicly (they feed on the wind) so it's impossible to follow them. They are lovely birds. They are not native to NZ. They flew/blew over from Australia. See here for more info: https://www.nzbirdsonline.org.nz/spec...
