Help find our House Martins

Posted August 1st, 2017 at 12:54 am in Conservation

The Dartmoor House Martin Project is going strong and there's still time to log your sightings of active nests on the website: www.dartmoorhousemartins.org

You've missed this year's series of talks by naturalist John Walters in Ashburton, Princetown and Yelverton but there's still time to join John when he hosts a couple of evening walks to see the birds and discover more about them in Buckfastleigh and Lydford. Look out for dates and details on the Dartmoor National Park website: http://www.dartmoor.gov.uk/ or on our What's On pages.


What do Dartmoor Cuckoos eat?

Cuckoos across Devon have experienced a significant decline over the past few decades and it's likely that there are now no breeding birds anywhere except Dartmoor and Exmoor. On the moors, Cuckoos that parasitise Meadow Pipits are still holding on but those that used to lay their eggs in Dunnock's nests seem to have disappeared.

One explanation might be the lack of food for returning Cuckoos, particularly big hairy caterpillars such as those of Drinker Moth and Fox Moth. The best way of telling what Cuckoos eat is by collecting faecal samples from adult and juvenile Cuckoos and testing the DNA. But that's easier said than done. To find out just how tricky it is, read Stuart Croft's fascinating blog on the RSPB website here:
