Mass Raptor Poisoning

Allen Lambert worked as a gamekeeper on the Stody estate in north Norfolk. On 1 October 2014, he appeared at Norwich Magistrates' Court and was found guilty of two charges relating to the killing of 10 Buzzards and a Sparrowhawk on the estate and possession of pesticides and other items capable of being used to prepare poison baits.

A key part of the case for the defence was the idea that the number of dead Buzzards found was too high to have been achieved through illegal poisoning in one area and that the carcasses must therefore have been ‘planted’ on Mr Lambert. When the experts were consulted, however, BTO (British Trust for Ornithology) quickly provided the robust evidence that refutes this claim.

Counts of Buzzards in north Norfolk from the same time period as the crimes took place (March–April) were extracted from BirdTrack and mapped.

On the map orange dots represent counts of 10–14, red dots 15–20. These counts were logged by birdwatchers (I submit sightings to Birdtrack) during their day-to-day birding. Who could have foreseen that the simple action of recording sightings in BirdTrack would realise the immense value of such ‘normal’ observations in this way?

As well as proving beyond doubt that double-figure counts of Buzzards are a regular occurrence in Norfolk these days, data collected by BTO volunteers was used in court to highlight the recent population increase and range expansion of Buzzard. Data from Bird Atlas 2007–11 and the Norfolk Bird Atlas were used to show the eastward spread and increasing population density since the previous breeding atlas in 1988–91, while CBC/BBS data spanning 5 decades helped emphasise the recent, dramatic population increase.

It's not unusual for birdwatchers' records, provided impartially, to find valuable applications like this, though it's the first time that BirdTrack data have been utilised in such a case. Fantastic!

UK's Wild Bird Population Continues to Decline

The number of wild birds in the UK is still falling despite efforts to protect them by changing farming practices. Conservationists have urged the environment secretary, Owen Paterson, to use the money newly available from the EU's common agricultural policy to step up protection measures.

Since 2003 there has been a 13% decline in the population of farmland birds. In the five years to the end of 2012 the decline was 8% overall. The decline has slowed according to the Wild Bird Indicator statistics released by the government last Thursday and some species are in better health than they were in the 1970s when data began to be comprehensively collected. However, conservationists (including me) are concerned that the drop in numbers is continuing with a halving of farmland bird numbers in the past 40 years. Woodland bird numbers are down 17%.

Turtle Doves have had their lowest level of sightings since records began. Lapwing numbers are down by nearly two thirds since 1970, while Corn Buntings are down 90% in the same period and the number of Skylarks is down by well over half. These are truly alarming statistics.

Farmland birds suffer from intensive agriculture as farmers often remove or drastically cut back the hedges and trees where many of them live. Pesticides can leave them with less prey and a lack of wide field margins cuts down on habitat.

The decline in farmland birds has slowed and wildlife friendly farmers who put conservation measures in place on their land are to be congratulated for their hard work. But funding must be there for these measures to continue. Under reforms to the CAP that were agreed this summer our government has the ability to divert some of the millions of pounds available (which come ultimately from taxpayers) to environmental stewardship schemes to reward farmers for good practice. Needless to say, Owen Paterson has still not said how he intends to allocate the funding and given the governments freedom of action under the new rules, much of it could go to farmers not based on their practices but on the amount of land they farm, as other subsidies are.  Without Paterson's help farmland wildlife will continue to struggle along with those farmers trying to help.
