My first thought, judging by the dark blue-green of the wings, was that this must be a young kingfisher. It also had copper around the wingtips and lower rump. Then when I turned it over, I saw the white breast barred with black and immediately realized it was a Shining Cuckoo (Chrysococcyx lucidus).
Some books identify this as of ‘sparrow size’ and I can state absolutely that the shining cuckoo is definitely bigger than a sparrow (16cm + I’d say). This bird had a long split down the front of its chest, so I don’t think it was killed by my cat (now 20 yrs of age) – more likely blown into my cottage.
Shining cuckoos migrate down to New Zealand from the Bismarck Archipelago (New Guinea) and Solomon Islands in the summer to breed, using nests of the Grey Warbler (Gerygone igata) to lay their eggs – one per nest – and they leave the tiny warblers to raise their kids. Fortunately, by the time the shining cuckoos are ready to lay, the warblers have already raised one litter, so all is not lost (isn’t nature wonderful?). But the young shining cuckoo definitely puts paid to the warblers’ second litter.
I had never seen a shining cuckoo ‘in real life’ before, and didn’t know I had them here, though I’ve always known we had grey warblers, because I heard them. I used a pair of shining cuckoos as part of the wildlife interest in one of the 36 paintings I did for the book ‘Taketakerau The Millennium Tree’, which I illustrated in 2011. Here’s the painting:

I’ve now heard the shining cuckoo’s call on New Zealand Birds Online, and identified it as a call I’d been hearing lately. Was listening to the call outside this morning when I saw a fast flash of green wings across the grass to the trees where the sound was coming from, so I feel happy to know that the mate of the bird that lost its life (which was a female, I think) is not alone.
They are very fast fliers and spend much of their time hidden in the trees. So often one just doesn’t see these birds !
