Seasonal migration<\/strong><\/p>\n

This is a movement between breeding and non-breeding ranges. Summer visitors arrive from the south and winter from the north.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Latitudinal\u00a0migration<\/strong><\/p>\n

Longitudinal migration<\/strong><\/p>\n

Irruptions\u00a0<\/strong><\/p>\n

Irregular migrations are caused by a lack of food and water, resulting in large numbers of birds flying to unfamiliar areas.<\/p>\n

Nomadic migration<\/strong><\/p>\n

Like irruptions, these result from a lack of vital resources, but birds cover shorter distances and stay within a familiar range.<\/p>\n

Altitudinal migration<\/strong><\/b><\/p>\n

This is a movement from high to low ground during the colder months, usually over short distances. Skylarks do this.<\/p>\n

Moult migration<\/strong><\/b><\/p>\n

Drift<\/b><\/p>\n

Reverse migration<\/strong><\/p>\n

This is most frequently seen in autumn when young birds become confused, flying against their expected route.<\/p>\n

Dispersal<\/strong><\/p>\n

This occurs when juvenile birds are forced to leave fledging grounds to find new territory \u2013 it\u2019s not a true migration.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Redwing<\/strong><\/p>\n
Similar in appearance to the song thrush and mistle thrush, the redwing is the smallest of the thrush species found in Britain. It can be identified by the orange-red patches under its wings, and by the creamy stripe over its eyes. Only a couple of pairs nest here, with the majority arrive in here in autumn to feed on berries, before leaving again in March and April.<\/p>\n
