Why is this Vogelkop Bowerbird (Amblyornis inornata) delivering flowers? Rather than being showy himself, he’s decorating the “lawn” of his twig hut with carefully chosen ornaments. This impressive structure is not a nest. It’s a bower—constructed and maintained for the sole purpose of impressing females. Local females regularly visit neighborhood bowers to compare design choices, then base their mating decisions on which displays make the best overall impression. For bowerbird males then, it’s the architectural skills that count. Vogelkop Bowerbirds are native to Western New Guinea.
