Wild bird populations in the UK, 1970-2013

DEFRA has published its statistical release about our bird population.

The full report can be downloaded here.

This is the Executive Summary

Overall, breeding bird populations in the UK have declined compared with 40 years
ago. In 2013, the all-species index was 12 per cent below its 1970 level, and there was a
small but significant decline of five per cent from 2007 to 2012. However, trends vary
between individual bird species, between habitat types and between groups of species
that share the same habitat type.

By 2013, the UK breeding farmland bird index had fallen by 55 per cent to a level 
less than half that of 1970. The largest declines in farmland bird populations occurred 
between the late seventies and the early nineties, but there has been a statistically 
significant on-going decline of ten per cent between 2007 and 2012.

By 2013, the UK breeding farmland bird index had fallen by 55 per cent to a level 
less than half that of 1970. The largest declines in farmland bird populations occurred 
between the late seventies and the early nineties, but there has been a statistically 
significant on-going decline of ten per cent between 2007 and 2012.

In 2013, the UK breeding water and wetland bird index was 17 per cent lower 
than its 1975 level. There was a significant decline in the smoothed index of 12 per cent in 
the short term between 2007 and 2012.

Seabird populations in the UK have fallen by 24 per cent since 1986; this is the 
lowest level recorded. Most of the decline has occurred since 2003; there has been a 
decline of nine per cent in the short term since 2008.

In the winter of 2012-13, the wintering waterbird index in the UK was almost 
double its 1975-76 level (up 95 per cent). The index peaked in the late 1990s and has 
declined since, with the smoothed index falling by almost five per cent between 2006-07 
and 2011-12.

Steve Lovell – “Extremadura”

30 of us were treated to a beautifully photographed tour of “Green Spain”. Extremadura, the land beyond the Douro, is the largest autonomous region of Spain but has the lowest population density of only 25 people per square kilometre. Unlike the coastal regions of Spain, winter does not attract a multitude of northern sun seeking humans but 12 thousand cranes will fly down from Scandinavia and the reservoir lakes are covered with thousands of visiting water birds including an estimated 40,000 shovelers. Steve’s route took us through all the varied habitats, from the rocky hills and forests of the north to the rolling heaths and “dehesas” of the central and southerly regions and through the irrigated agricultural lands in the east. The “dehesas” (meadows, pasture) deserve special mention: they are managed areas of thinned holm oak forest and go through cycles of cereals, pasture and scrub, which is then eaten by the Iberian black pigs, which in their turn are eaten by Spaniards. Hoopoes are well camouflaged against the golden landscape but nuthatches and other colourful birds are easily seen. Drifts of French lavender and red poppies add colour, lupin and clover add nitrogen, and as Steve pointed out, the botany of this area is staggering in its variety and colour.

Extremadura is a bird watcher’s paradise. The following are just some of the species that Steve had photographed: blue throats, assorted buntings, purple herons, purple swamp hens, storks, sparrows, kestrels, black kites, little and great bustards, griffon vultures, azure wing magpies, bee-eaters, etc. etc., even a Spanish imperial eagle. Large lizards, oil beetles, dragon flies, frogs and swallowtail butterflies were caught in Steve’s lens, as well as deer and a very handsome fox.

The government of Extremadura is working very hard to promote the area as a destination for eco-tourism and it has the greatest number of Special Protection Areas in the whole of Europe. One road, known as “Roller Road”, has even been kitted out with bird boxes on every telegraph pole and is successfully attracting large number of these beautiful birds. Reserves are well provided with information boards and helpful staff, the biggest reserve being Monfragüe National Park.

Spring is the best time to visit but winter is wonderfully quiet and there is plenty to see. If you want a break from ‘nature’, then you can drive down the “Silver Route”, named after the ‘conquistadors’, such as Pizarro and Cortés, who came from this area. You can visit the holy pilgrimage town of Guadalupe, the unspoilt listed heritage city of Cáceres and marvel at the Roman theatre still standing and still used in the town of Mérida.

Thank you Steve, for opening our eyes to the beauty and fascination of Extremadura.
