This is really important, because we should do a survey of the whole of Tisbury, but there just aren't enough of us to plan that. So please, look out, listen out, let us know! On Facebook or to email@example.com (apology for previous typo).
They're one of three breeds that come thousands of miles to breed here, and then go thousands of miles back to southern Africa to feed during our winter. Of course others do this, but these three seem particularly to be the sound of our summer.
At this time of year, just like a school-leaving prom, they're trying out their wings and building up strength for life as adults.
This is them in their nests -
- but it's not just the parents who have to squeeze in, it's up to four babies-kids-teenagers!!
It's not surprising that all through the night you can hear one of the most beautiful sounds in nature - a little constant cheep-burble, I guess saying 'shove over a bit, your claw's in my ear' or something like that.
