Recaptures For the year 2790 new birds of 17 species were banded, this is our lowest total since 09/10 and well below the 5 year average but only slightly below the 9 year average.

The number of birds recaptured was higher than the last 2 years but well below 10/11 with the highest number of Greenfinch recaps since then.  

Species caught ranked by the number of new birds banded.

1 Silvereye - 1097 (752) The  No 1 bird every year but numbers down on both the 5 yr & 9 yr average
2 House Sparrow - 822 (134) Usually at No 2 and above both the 5 yr & 9 yr average.
3 Greenfinch - 313 (103) Mostly at No 3 but has occasionally supplanted H Sparrow at No 2
4 Chaffinch - 140 (9) Usually at 4 or 5 and very close to the 5 yr average but slightly below the 9 yr. The number of recaps well below recent years.
5 Blackbird - 111 (70) usually ranges between No 4 & 6. Below both the 5 yr and 9 yr averages, there appears to be a drop in Blackbird numbers about the city in recent years.
6 Goldfinch - 75 (6) numbers up on recent years mostly due to good numbers of Juv's caught at stream sites.
7 Grey Warbler - 59 (17) the big mover with the ranking last year at No11. Great to see this little beauty doing well.
8 Tui - 46 (5) Slightly down on most years mainly due to catching effort rather than lower numbers.
9 Dunnock - 42 (13) About an average number.
10 Starling - 37 (25) Following the trend of recent years of lower numbers.
11 Fantail - 31 (4) Slightly below average but can be hard to catch and even harder to recapture.
12 Yellowhammer - 12 (0) Well below the average but the numbers of this species fluctuates from year to year. 
Small numbers of Song Thrush, Eastern Rosella, Kingfisher, and Bellbird were also caught but no Redpolls. 





Birds caught or sighted after 5 years from banding

House Sparrow 1 1 2
Chaffinch 1 2 1
Greenfinch 0 2 0

Forty two bird were recaptured or sighted by colour bands during the year. This is up on recent years mainly due to an increase in old Silvereyes caught, many during the influx of birds in July. Many of the Tui reported are of colour band sightings, this number is expected to decrease over the next few years as the number of colour banded birds reduces.
