Report of the COG Woodland Survey at Majura , 30 June

[Kim Farley via Canberrabirds <>]

I don't think it's a trend -  just an oddity of different conditions.

To answer Phillip's musing thought. The multiple sites are surveyed in the same order every time, and starting at the same time of day, 10 minutes each site. We also note birds heard off the site, but depending on the size of a Noisy Miner territory we may or may not hear them I guess.

Is it reasonable to suggest it could be a matter of random timing. Whole groups of Noisy Miners may move around and thus just most of them just be somewhere else at the time of the survey.

How interesting about the Noisy Miners, Kim.  Not many reports of that trend.  I wonder if they are deterred by something in the Defence area.  They have certainly taken over on the adjoining Fairbairn Golf Course which is brimming with potential colonizers.  Not many trees just over the fence, though.  More like Stubble Quail country.

On Friday the 30th of June, Barbara Allan and I visited the Majura Defence Training Area for the quarterly COG Woodland Survey. It was a sunny and calm morning after the very cold weather of the previous days.

Overall, we saw only 25 species at the eight sites we surveyed. Barbara said this is likely the lowest number of species ever seen during her many years doing the survey. On the other hand, we saw more water bird species than is usual, including Aust Grebe on a dam that has never produced a single sighting of any species. We also counted 65 Pacific Blacks Ducks, with most of these at just the one site.  And as with the March survey, there were far fewer Noisy Miners than has been usual. Five Scarlet Robins were recorded, along with Striated, Buff-rumped and Yellow-rumped Thornbills at multiple sites and along the tracks between sites
