Fears about the impact of last December’s severe weather, the coldest in 100 years, were unfounded. The drop in small bird populations witnessed in the RSPB Birdwatch of 2010 during the Big Freeze was rectified by excellent breeding conditions in the following spring. Small birds in recovery notably include goldcrests, long-tailed tits and coal tits.
Another interesting result of the survey were the numerous sightings of waxwings, reflecting both the large numbers migrating from Scandinavia this winter and the “bird-friendly” berry-producing vegetation people are increasingly planting in their gardens. A record 600,000 people took part. The results compared with last year:
- House sparrow – 4.2 birds per garden in 2011, rise from 3.8 in 2010
- Starling – 3.9, up from 3.1
- Blackbird – 3.3, stayed the same
- Blue tit – 3.2, up from 2.6
- Chaffinch – 2.4, up from 2.2
- Wood pigeon – 1.9, stayed the same
- Great tit – 1.6, up from 1.4
- Goldfinch – 1.5, up from 1.3
- Robin – 1.5, stayed the same
- Collared Dove – 1.3, stayed the same at 1.3
The oldest osprey of the UK – and probably the world – has returned to her eyrie in the Scottish highlands. When she left for West Africa at the end of last summer, no one expected her to return. At 26 she’s lived 3 times longer than most female ospreys. In her life she’s laid 58 eggs and hatched 48 chicks, a massive individual contribution to the survival of ospreys in Scotland, where there are still only about 200 breeding pairs. The questions now are if her mate will return and if she is still fertile. Events can be followed on the 
Otters, water voles and fish are all benefitting from the improved quality of the UK’s waterways, now described as the cleanest since the industrial revolution. Since almost disappearing from the wild in the 1970s, otters are thriving, particularly in the south west of England, Cumbria and Northumberland. The population of water voles, highly precarious in the 1990s, is also beginning to recover. The good results of stricter pollution controls and extensive conservation work are set to continue in the new year with the introduction of new European water quality directives.
