Singing lessons for a bird? It seems implausible in the wondrous world of nature but that is the prospect in store for captive-bred teenage honeyeaters looking for love.

They’ve discovered the captive-bred birds do not know how to sing the right love songs to attract mates. Programs to breed rare species in captivity to … [Read more...] about Love is in the air for regent honeyeaters

Like customers in an up-market beds and bedding store, forty-spotted pardalotes have been presented with a range of home comforts to make life a little more comfortable. The forty-spot initiative is not just about the supply of soft bedding, though. The bedding contains a pesticide which is ridding the pardalote chicks of a parasitic fly decimating their number. Found only in Tasmania, the forty-spotted pardalote numbers probably no more than 1500 birds, most found in … [Read more...] about Forty-spots can now rest assured
