Monitoring Bar-tailed Godwits on The Wash

Bar-tailed Godwits (Limosa lapponica) are large waders which have a wide distribution across several continents. Five subspecies are currently recognised plus a sixth recently proposed as yamalensis (Appleton 2021). Bar-tailed Godwits are long-distance migrants and one subspecies (baueri) makes an incredible non-stop migration from Alaska to New Zealand over the Pacific Ocean lasting many days.

Two populations of Bar-tailed Godwit use The Wash: lapponica breeds from northern Fennoscandia eastwards to western Russia and the Taymyr peninsula and moults on The Wash in autumn, with most birds staying to spend the winter; taymyrensis breeds further east reaching central Siberia and passes through The Wash on migration to its wintering sites, as far south as West Africa.

WWRG: back in the Bay

So it’s three years since the WWRG team last came out to Delaware. Back then we bought our plane tickets and booked cars early as we were sure we would be coming over – then the World shut down… The only good thing was we got most of the costs of the flights and cars back. Into lockdown and virtually no fieldwork – it’s been a rough two years in many ways and we are still not out of the woods now – but we’re very grateful for vaccinations. This year we had to do supervised Covid tests and are living in a ‘bubble’ in a separate house – although we can use the basement of Penguin Manor to go and do data entry, but there is not too much of that yet.

The Norwegian Connection: a tale of two journeys

One of the most visible birds on The Wash beaches must be the Oystercatcher. With its distinctive black and white plumage, orange bill and strident ‘kleep’ call, it’s certainly hard to miss! But where do ‘our’ Oystercatchers go when they leave The Wash? The map summarises the international movements of ‘our’ Oystercatchers – the red triangles are birds ringed abroad and found on The Wash, the blue dots are birds we ringed that were found abroad. It is clear that there is a really strong connection between The Wash and Norway – which is where most of the Oystercatchers wintering on The Wash go to breed. Most of these reports are of metal-ringed birds but, in recent years, we and other groups have used colour marks and tags to track movements in greater detail, and these sometimes produce very rapid feedback.
