Bird of the Year: Barn Swallow

Date of Issue : 21 April 2011

The barn swallow (Hirundo rustica) is a passerine with blackish blue upperparts, off-white underparts, rufous forehead, chin and throat and a deeply forked tail, of which 100,000 to 200,000 pairs live in Estonia. It mainly nests in man-made structures, such as stables, attics and under the eaves of buildings, where it builds a nest of mud, clay, stalks and saliva.
