This proved an interesting behavioural observation. In a small flock there was a mix of adults (males and females in non-breeding plumage) and juveniles. Interestingly one of the juveniles was behaving like a territorial male toward a mature male, constantly harassing it and at times actually flying at it and attacking it as pictured in one of these photos.

Not seen these before in Gisborne.
First heard them cooing in the morning and after a while saw one on the roof as the sun was rising. According to authorities first introduced to Auckland and have spread to Bay of Plenty and Opotiki. Now several birds here ? whether escaped from captivity or migrated south from BoP.

Is anybody monitoring the spread of these, and do they take over food or habitat from native birds?

I first saw a few of these several years ago, maybe half a kilometre down my street, now there are dozens of them around home and they seem to have filled the entire valley.

Ephemeral wetland formed by water from a stream trickling into the gravels on the beach. Lasted a few years but last time I saw it, it was dry and full of weeds. Note tadpoles in one of the photos.
Deleted this observation entered earlier because the photos weren't showing up and have tried again.
