Migration steps-up a gear.

The weather forecast for this weekend looks almost perfect for a spectacular migration event. High-pressure over Scandinavia and low cloud along parts of the east coast of Britain are a recipe for large numbers of common birds to be on the move, and for some rather more scarce birds altogether, as the BTO migration blog explains.

BirdTrack App video guides

For iPhone and Android smartphone users, the free BirdTrack App offers a great way to log sightings in the field, saving the step of adding records online later. It's straightforward to use and comes with built-in help pages. For those who haven't yet tried it or who would like some guidance, we have created video tutorials for the iPhone and Android versions.

BBS results - wagtail declines

The recently published Breeding Bird Survey (BBS) results reveal wagtail species are in long-term decline in the UK, House Sparrows are thriving in Wales, Linnets are struggling in Northern Ireland and House Martins are up in Scotland but down in England. The BBS results allow us to see the extent at which bird populations are increasing or decreasing, which is fundamental to bird conservation. Thanks to our volunteers we have been able to monitor the population changes for over 100 bird species over 3,600 sites. Read the BBS report

Will Chester the satellite-tagged Cuckoo be the next to cross the Sahara Desert?

Successful southward migration for our Cuckoos

Most of our satellite-tagged Cuckoos are having a successful southward migration this year, possibly as a result of them being in good condition when they left the UK due to our good spring and early summer weather. Most birds have already successfully crossed the Sahara Desert. However, Chris the Cuckoo is still in Italy and appears to be running late. This time last year he was south of the Sahara Desert. You can follow our satellite-tagged Cuckoos here.
