This week's birds are the blackbird and the tūī (http://www.doc.govt.nz/global/training-courses/bird-id/birds.swf).
Only the male blackbird is actually black. It also has a distinctive orange beak. The female blackbird is brown with a variegated underside. Blackbirds mainly forage in the garden, looking for insects, earthworms, snails, and spiders. They also eat a range of seeds and fruit.
Tūī eat nectar from flowering plants, such as flax. They also eat insects and fruit. Tūī can imitate noises and can also sing at a pitch that humans can't hear, so it looks like they are singing, but no sound is coming out! (From 'In the Bush', N. Barraud and G. Candler, 2015.)
