It might only be the end of January and the days might still be short but some of our birds have already begun their spring migration. Fieldfare and Redwing have started moving north and east, with numbers beginning to build in eastern Britain. Siskins have started to turn up at garden feeding stations as they too make their way back north, and the first of the BTO satellite-tagged Cuckoos has begun the long journey back to the UK.
Cuckoo PJ spent most of the winter in Angola but since leaving there last week he has travelled 1,600 km (1,000 miles) north and is now in Cameroon. He should head west from here before once again turning north and crossing the mighty Sahara. You can follow him as he makes his way back home during the next couple of months.
Auks are also on the move and Guillemots and Razorbills could be back prospecting on their breeding ledges any day now. Look out for them at coastal watch points.

One of the biggest surprises of the autumn 2017 migration was the unprecedented arrival of Hawfinches into Britain. The exact number is difficult to calculate as the birds are so widespread and mobile, but it is thought in excess of 1,000 birds have arrived here and that the true figure might even be as high as 5,000. The estimated breeding population is only 500 – 1,000 pairs, so this is an incredible increase. The BirdTrack graph shows how spectacular this arrival was compared to the historical average for the species, and they are still being seen across the UK. Some of the largest concentrations are currently to be found in Surrey, Sussex and Shropshire.

It’s only a matter of time before the wintering geese and wildfowl begin to head north and east too. February is the peak month for Pintail, Goldeneye and White-fronted Goose all of which will be steadily heading to the breeding grounds in Northern and Eastern Europe. Male Goldeneyes at this time of the year can often be seen performing their display which involves throwing their heads backwards, then forwards – extending the neck as they do so – in readiness for the breeding season ahead. Other wildfowl will be getting in to flocks ready to depart when the weather is favourable, with some heading across Europe whilst others,such as Whooper Swans and Pink-footed Geese, will be heading to Iceland and Greenland for the summer months.
