The 20014-15 year - A bit below average

I have just collated our banding stats for the banding year 2014/15 which closed on 31 March.
It was a reasonable year with a total of 3079 new birds banded and 944 recaptures. Both these figures are slightly below both the 5 and 10 year averages. For the first time Silvereye have been knocked off the top perch replaced by House Sparrow which is usually No 2 candidate.

Significant movements in the table above are shown - up in Red and down in Blue. The figures beside the total for each species indicates their ranking for the year.

Species caught in order of the number of new birds were ( recap totals in brackets)
No 1 House Sparrow - 1056 (159) The usual No 2 species.  They have had a huge breeding season with a large number of juveniles caught Nov to Feb.
No 2 Silvereye - 1001 (527) The first time Silvereye hasn't been No 1 and the lowest total in 10 years. The mild winter meant that very few were caught at our usual winter sites.
No 3 Goldfinch - 206 (17) The big mover for the year, up from 6 last year and well above average with more than double both the 5 and 10 year. Large numbers of juveniles were caught over the summer at our stream sites.
No 4 Greenfinch - 205 (103) Well down on both the 5 and 10 year average. Usually ranked at No 3
No 5 Blackbird - 178 (94) Slightly up on average.
No 7 Chaffinch - 152 (17) Usually ranked at 4 although numbers were about average.
No 8 Tui - 71 (10) Our equal highest total and continues the trend of rising numbers.
No 9 Dunnock - 55 (17) About average.
No 10= Starling - 47 (33) Down on the last couple of years but still about average.
No 10= Fantail - 47 (5) Down on recent years, possibly affected by the dry year.
No 12 Grey Warbler - 41 (6) About average
No 13 Song Thrush - 12 (1) Our highest total ever.
No 14 Eastern Rosella - 3 (0) A species just starting to show on the radar.
No 15 Yellowhammer - 2 (1) This species is very variable and didn't come to town this year.
We also caught 1 each of Kingfisher, Magpie and a Californian Quail. No Redpolls were caught during the year.

There was a good increase in the number of birds caught over 5 years from banding including our first Yellowhammer.

The number of birds recovered dead was down on the last few years, probably due to the mild winter.
