Wellington 2015 Roundup

The Group had a successful year's banding in 2015 at most sites around Wellington and most species numbers were near average. These numbers are for the calendar year 2015. The total number of birds banded for 2015-2016 banding year will be calculated as at 31 March 2016.

Wellington Zoo

At our main banding site at the Zoo we caught a total of 842 new birds and made 245 recaptures. Below are numbers of the birds caught in 2015 and over the last 5 years. This includes the 5 year and 16 year totals and averages. The numbers in blue are the yearly ranking of the various species.

Birds in order of rankings of new birds caught with recaps in (brackets).
No 1 Silvereye - 304 (130) well up on last year, above both the 5 & 16 year averages.
No 2 House Sparrow - 154 (36) up from 3 last year and above average.
No 3 Greenfinch - 117 (35) about average 
No 4 Goldfinch - 87 (12) 
No 5 Chaffinch - 82 (16)
No 6 Blackbird - 41 (7) above average but recap numbers down.
No 7 Tui - 12 (0) a little down on last few years and surprisingly no recaps although we had a number of recoveries.
No 8 Dunnock - 12 (7) exactly average for both 5 & 16 year.
No 9 Fantail - 11 (1) below average.
No 10 Grey Warbler - 7 (1) slightly above average.
No 11 Yellowhammer - 7 (0)
No 12 Song Thrush - 4 (0)
No 12 Starling - 2 (0) well below average as was the catch at all our other sites. Don't know why as there appeared to be plenty of Starlings around.
We also caught 1 Eastern Rosella.

Island Bay.

The catch rate at our Island Bay site in 2015 at 353 new and 62 recaps was much lower than previous years primarily due to far fewer sessions being held there. It is also very noticeable that it has become a far less diverse site than in previous years, with the almost complete collapse of Greenfinch and Silvereye numbers in particular. This is mostly due to a change of feeding by the owners of the property.

Prince of Wales Park.

We had 5 sessions at the Prince of Wales Park banding 158 birds of 7 species with House Sparrows and Goldfinches being the most numerous.

Hornsey Rd.

Bird numbers at the various Hornsey Rd sites were down on most years with Silvereyes, which are the most numerous, being slightly up on last year but only came to feeding tables for a short time. All other species were well down especially Starlings.

There was also some banding done at the Karori Cemetery and at a couple of other sites.
