A foreign recovery.

Some nights ago I caught a ringed nightjar with unidentified ring. When I checked were he was ringed I got some information about him. Hi was ringed at Ottenby birdstation this spring and now he is in my areas.
Once previously I have caught a foreign bird, and that was my first year with nightjars. That bird was ringed at Utklippan birdstation 4 year Before I Catch him-

The Ottenbybird was an second year bird.

A night with nightjarrecord and some ageing.

Yesterday it was a perfect night for nightjaring. Calm, varm and some clouds do the night perfect to catch nightjars. And it starts very good early in the evening with 3 nightjars before midnight and after midnight 6 more. Totaly 9 nightjars in one night do this night to my best ever and I had much work until the dawn to drive to different place and put up my mistnet in good places.
One of the birds was an old friend from 2010 and I have recover him before over the years. When I ringed him he was a 2:d year bird or older and now hi is over seven year old.

Several nightjar nests found and predation.

We have found several nest and have now ringed some nestlings to. We have much predation and at one nest we rigged a trailcam and luckily (or not luckily) that nest was predated. When I look at images from trailcam suddenly a Buzzard poses in front of the cam. And to the Pictures after that there was no nestlings left. In the evening the adults came to the nest and found it empty.

 Two nestlings in this nest was around a week old.

 Close up nestling.

 The male was caught to the nest and was a recover from 2013 and was ringed in another place a bit away.

 The predator was a Buzzard and the nest is just behind him.
