On our train ride up by Kawakawa the other day we spotted this Kawaupaka | Little shag in trees by the line: 🐦

the little shag’s diagnostic short-billed and long-tailed silhouette, along with its small size and stubby yellow bill. Shape alone is sufficient to identify a little shag.

At least, I think that's what this bird is. It was quite little and has a stubby yellow bill.
