Young
Semi-altricial, nidicolous. Fledge in about 63 - 70 days. Fed initially by female then by male also.
Subspecies
Occurs on all continents except Antarctica.
West Indian taxa glaucops, insularis and nigrescens formerly subspecies of Barn Owl (Tyto alba), now shown to be separate species, Ashy-faced Owl (Tyto glaucops). Some authors separate only glaucops, retaining other two subspecies in present species.
Validity of many proposed subspecies considered too doubtful to be upheld: in Europe, pusilla, kleinschmidti, kirchhoffi and hostilis merged with nominate, and rhenana with guttata; Madagascan hypermetra with African affinis; island populations everetti, kuehni, bellonae, lifuensis and lulu with widespread Australasian delicatula; Bahamian lucayana with pratincola; and, in Neotropics, Colombian subandeana with guatemalae, stictica with contempta and hauchecornei with tuidara.
Also, current separation of niveicauda from furcata and of guatemalae from pratincola perhaps doubtful, and continued separation of bondi may not be tenable; separation of hellmayri from tuidara based on size characters questionable. Furthermore, poensis possibly not separable from affinis, in which case poensis (as older name) has priority over latter. Northern African nominate subspecies birds sometimes placed in erlangeri; birds from southern Myanmar to Indochina sometimes placed in javanica, but seem better included in stertens. Melanesian populations, currently covered by 3 races (delicatula, crassirostris, interposita), may merit further splits. Several well-marked insular races (e.g. detorta, thomensis, deroepstorffi, punctatissima and possibly others) may be separate species.
The following 31 subspecies are recognised:
