(Common) House Martin (Delichon urbicum) Andorinha-dos-beirais

The House Martin is another summer visitor who is almost never found far from Man. It builds a closed mud-built nest stuck to the side of a wall or under the eaves of a roof with a tiny side-entrance hole for access.

It is appreciably smaller than the Barn Swallow and, even though they often nest and feed in close proximity, lacking both the chin-strap and the long tail streamers, it is difficult to get them mixed up unless one really isn't trying! 

However, it's a different question when Red-rumped Swallows are nearby as juvenile Red-rumps have a short tail, a white rump and no chinstrap, so care shoyuld be taken to avoid a misidentification.
