Study of Swallow Roost 2003-2008
Little Givendale Farm
The ringing at Little Givendale took place at the edge of Maize fields and contributed to the BTO Swallow Roost Project (2002 - 2006) aiming:
-
To describe the seasonal pattern of use of Swallow roosts throughout Britain and Ireland and the types of habitats that are being used.
-
To describe the physiological strategies of British and Irish Swallows during the pre-migratory and migratory phases by collecting data on weight, fat accumulation and body condition.
-
To supplement existing information on movement patterns by collecting data on roost catchment areas and movements between roosts.
In order to make the data comparable across Europe ringers catch and accurately measure up to a hundred birds each visit ( minimum of 30 birds ). To allow the catchment areas of roosts to be identified, ringers are also being encouraged to ring nestlings during the breeding season.
Although the study ended in 2006, ringing continued at the Little Givendale site in 2007 and 2008
