Migration blog review of 2021

16 Dec 2021

Whilst 2021 was a stop start year for many of us the same could be said for migrating birds, but for very different reasons.

Migration blog – Winter

As we get ever closer to the end of autumn the pace of migration steadily slows, and as the daylight hours shorten so does the variety of birds on the move.

Migration blog (22nd – 28th October)

Many bird watchers have been lamenting on what a poor autumn it has been so far for migration, with numbers of common, scarce, and expected rare species down on what would normally be expected.

Migration blog (1st – 7th October)

October is for many birdwatchers their favourite month of the year, with a real mix of common migrants, winter visitors and the occasional mega rarity thrown in for good measure.

Migration blog (24th – 30th September)

No sooner had I pressed the button to publish the last migration blog, the weather forecast for the week changed completely – the expected easterlies were replaced by westerlies and as a result reports of many of the common migrants fell away.

Migration blog (17th - 23rd September)

Many of our summer visitors will be well on their way by now with Swallow, Willow Warbler, and Swift sightings rapidly falling in the last couple of weeks. Whilst some species such as House Martin will be around for a bit longer, over the next week these too will depart en masse before the cooler conditions of autumn really start to take affect.

Migration blog (10th – 16th September)

With the past week seeing a rise in temperatures across much of Britain and Ireland the pace of migration continued to grow, with the settled conditions providing migrant birds with clear skies and favourable winds.

Migration blog (3rd – 9th September)

With the first days of Autumn upon us and the breeding season over for many species, the focus is now on preparing for the coming winter months. Whilst some species will remain within Britain and Ireland, others will be leaving or passing through en route to wintering grounds further south.

Migration blog (21st May – mid-June)

It is certainly turning out to be a poor spring with consistently colder than average temperatures, showers and even strong winds for the time of year, all having a huge affect on migration.

Migration blog (14th – 20th May)

As the year progresses towards the end of May we get to the sharp end of spring migration, with arguably the greatest diversity of species and biggest number of birds on the move. The majority of birds that will breed across Britain and Ireland will already have arrived but there will still be some species yet to arrive, and those that have lagged behind such as last year's offspring that will be breeding for the first time this year. Britain and Ireland is also a stepping stone for many migrants that head further north to Iceland, Scandinavia or the high Arctic to breed.

Migration blog (7th – 13th May)

At last there is a forecast of warm southerly airflow for this weekend, a rare thing indeed this spring. This should unlock the floodgates and we should see a mass arrival of summer visitor and the exodus of any remaining winter visitors — it could be a busy weekend.

Migration blog (30th April – 6th May)

Another week dominated by cool weather was interjected by a spell of lighter winds at the start of the week that provided a scattering of common and scarce migrants, mainly along the south coast.
