Are common and roseate terns hybrid?

Hybrids between common and roseate terns have been recorded, particularly from the US, and the intermediate plumage and calls shown by these birds is a potential identification pitfall. Such birds may have more extensive black on the bill, but confirmation of mixed breeding may depend on the exact details of individual flight feathers.

Where are the Chinese crested tern symposia held?

Common Terns use a variety of habitats and may be found on coastal beaches, barrier islands, marshes, or inland lakes. They nest on sand, gravel, shell, or cobble in open areas with some scattered vegetation or other cover in which chicks can find shelter (Nisbet et al. 2017).

How many eggs do Arctic terns lay?

Where do marsh terns build their nests?

How do terns find and dig up eggs?

Studies show that terns can find and excavate their eggs when they are buried, even if the nest material is removed and the sand smoothed over. They will find a nest placed 5 m (16 ft) from its original site, or even further if it is moved in several stages. Eggs are accepted if reshaped with plasticine or coloured yellow (but not red or blue).
