Wood Sandpiper is a common species in Uppland during migration but as a breeding bird it is very rare. This morning I found a new breeding area for this species in a lovely setting. Tree Pipits, Cranes, Mistle Thrushes, Black Grouse and others can be heard in the background.

Wood Sandpiper - A rare breeding bird in Uppland

One after another of the tropical migrants arrive to Uppland. This Whinchat was actively singing on a clearcut and in the background you can hear a pair of Grey-headed Woodpeckers, Black Grouse, Wood Lark and others.

Whinchat singing from a clearcut

In 2025 I have visited four breeding sites where males were calling early in the year but there had been no signs of breeding later in the Spring. This was until yesterday when I stumbled upon a breeding pair. In this recording you can first hear begging calls of the female and later on what I gather is the female song (more the tone of a Wood Pigeon than in the male).

Lapland Owl breeding in Uppland also this year!

While recording a Whinchat I was lucky to stumble upon two Grey-headed Woodpeckers close to an aspen. I found a hole made this year and decided to put out a droprig the coming night. I was lucky to make a close-up recording of the calling male and at least two instances when they mated early morning.

Grey-headed Woodpeckers at home

Curlew has almost vanished as a breeding bird in Uppland but still a few pair linger on in boreal forest mires. I have for a long time wanted to record this disappearing song. This morning I was lucky!
