One ounce songbirds are mustering throughout hills and fields for probably the most unimaginable journeys in nature. Donald Trump might imagine Greenland is only a “large, lovely piece of ice” however for intrepid northern wheatears it’s a do-or-die summer season vacation spot.
All through Might, small numbers of the Greenland race of the northern wheatear – a brighter, bulkier relative of our native breeding species – move by way of Britain earlier than venturing out into the forbidding waters of the North Atlantic.

Within the face of prevailing winds, the birds battle for 30 hours earlier than touching down in Iceland. A fast stopover and the wheatears are off to the ice-pocked tundra of Greenland. Some will proceed into Arctic Canada.

Below the midnight solar, the wheatears will nest, fledge younger and, inside a number of weeks, start an equally gruelling migration again throughout the Atlantic to winter in sub-Saharan Africa. These 3,000 mile continuous flights are the longest carried out by any songbird over open water.
The Greenland wheatear’s migration is just equalled by its Alaskan cousin, which takes a clockwork route from African wintering grounds by way of the Center East into Siberia and throughout the Bering Strait into North America, a 9,000 mile odyssey.
This spring has seen a powerful upsurge of each native and Greenland birds arriving within the UK, giving birders alternative to get pleasure from their refined variations. Other than Greenland birds showing a number of weeks later, telling the pair aside requires detailed views.
To my eyes, the Greenland race is extra upright, longer winged, with the males having wealthy, mustard-toned throats and breasts together with brighter RAF blue upperparts. Separating the feminine races is greatest left to ringers with rulers and scales.
What impacts local weather change and international politics can have on the way forward for Greenland wheatears stays imponderable. Sadly, our native breeders have suffered a 37% decline over the previous 29 years.
One seemingly issue is the crash in rabbit numbers that preserve the wheatears’ grassland habitats in tip-top situation.
