What is the difference between oystercatcher chicks and gull chicks?

Oystercatcher chicks have very distinctive white bellies. First chicks hatch early to mid-April. Gull chicks are cream or light brown all over with spots; these spots are very clear on their heads. First chicks hatch mid-May. Gull chicks do not have the snowy white tummies.

Did the oystercatcher nest on the beach?

H F Witherby, editor of ‘British Birds’, considered this nesting record was worthy of mention in that journal, and it is recorded in Vol XXXIV No. 9, page 201. As this was the first time that the oystercatcher had come so far from its more conventional nesting habitat on the shingle beaches and sandhills close to the sea, one wondered why.

How long do oystercatchers live?

The longevity record for an oystercatcher stands at 40 years, one month and two days. Ringed as a chick in 1970, it was last caught by a bird ringer near the same place on the Wash in Lincolnshire in 2010. Amazingly, during all those years it has never been seen away from the site where it was first ringed.

Where can I see oystercatchers in England?

It’s possible to see oystercatchers on almost all coasts of the UK. Look for breeding birds in summer at RSPB coastal reserves. In winter, you can see large numbers on major estuaries, such as Morecambe Bay.

What kind of animal is an oystercatcher?

Where can I see an oystercatcher?

It can also be spotted on some inland waterbodies where it has started to breed. Classified in the UK as Amber under the Birds of Conservation Concern 4: the Red List for Birds (2015). Listed as Near Threatened on the global IUCN Red List of Threatened Species. The Oystercatcher is very noisy wading bird with a loud ‘peep-ing’ call.

High-rise living is an international trait in Oystercatchers; one of the birds ringed in Norfolk by the Wash Wader Ringing Group nested in a window-box in Norway and the practice of roof-nesting is common in the Netherlands. Oystercatchers look after their chicks for much longer than other wader parents.

Where do oystercatchers live in winter?

Originally a coastal species, the Oystercatcher has moved further inland over the last 50 years to breed on waterways and lakes. Most UK birds still spend their winters by the sea, however, and are joined by birds from Norway and Iceland.

Do oystercatchers migrate after breeding?

Recent tracking studies have revealed that oystercatchers make tremendously variable movements after the breeding season. Young birds do not follow their parents to wintering locations; in fact, young from the same nest may even migrate in completely different directions in autumn.

How common is monogamous mating in mammals?

Unless the male and female are perfectly monogamous, meaning that they mate for life and take no other partners, even after the original mate’s death, the amount of parental care will vary. Instead, it is much more common for polygynous mating to happen. Polygynous structures (excluding leks) are estimated to occur in up to 90% of mammals.

Do birds have to be monogamous to survive?

The most important thing is for chicks to survive and thrive, no matter how many mates are necessary. Polygamy doesn’t work for all bird species, however, and some birds, including many raptors, cranes and other long-lived species, are almost exclusively monogamous.

Why do birds have polygyny?

Polygynous structures (excluding leks) are estimated to occur in up to 90% of mammals. Polygyny in birds occurs infrequently when compared to mammals, as monogamy is most commonly observed. Evolutionarily speaking, polygyny in birds might have evolved because many females do not require male support to care for their offspring.

Are birds polygamous?

The majority of the world’s bird species can be considered polygamous to some degree, depending on how avian polygamy is classified.

What kind of bird is a Willet?
