Provide artificial nesting sites for songbirds
A replicated study in 1972-8 in Texas, USA (Brown 1981), found that purple martin Progne subis reproductive output did not differ between aluminium and wooden bird ‘houses’ (82% of chicks fledging from 275 pairs in aluminium houses vs. 86% from 116 pairs in wooden houses; average of 28 day nestling period for 82 pairs in aluminium houses and 67 pairs in wooden houses). Aluminium houses had six, 12 or 24 compartments and were commercially available, wooden houses were homemade but of similar designs, with 15 x 15 x 15 cm compartments.
