Wrens are one of the most common birds and widespread birds in the Bailiwick. They are found on all the major islands and also on some of the permanently vegetated islets where suitable cover is available. The Breeding Bird Survey recorded birds breeding in every square in Guernsey and this is presumably true for the other islands in the Bailiwick. Birds occur in most habitats on the island but seem to be most numerous in coastal and inland scrub, especially where there are areas of bracken. Although rare in occurrence, severe winters have been seen to severely reduce the population as in the cold spell of 1991, but populations usually recover within a few years.
