Laying more parasitic eggs could help evade host detection - new paper in Nat. Comms. 25/9/13
Our study shows that prinia (a host of the cuckoo finch) are able to remove eggs from their nests that look different to their own, but as the number of parasite eggs in their clutch increases they need a bigger visual difference to reject the foreign eggs. View the open access paper here.
Camouflage and Learning paper published in PLoS One 11/9/13
Our paper "Defeating Crypsis: Detection and Learning of Camouflage Strategies" has been published. The study shows how some camouflage stragegies are more vulnerable to predator learning than others - download -

Nightjar game online! 20/8/13
Our new online game has gone live! Play it here, and see how good you are at finding nightjars. We hope to use the data from the game to see how well it matches up with out computer models of camouflage.
Update: The game is spreading fast, 900 people played in the first 24 hours! Loads more are playing today with The BTO and BirdLife international helping to spread the word. Our server isn't so happy though...
Nest finding 17/8/13
We've just found our first White-Fronted Plover nest on the beach. These nests are supposed to be "easy" to spot because these birds normally make a scrape in sand surrounded by footprints. But this beach is almost entirely made of broken shells and the eggs blend in perfectly. Maybe that explains why this is such a popular beach with the White-Fronteds. See if you can spot the pair of eggs in this shot:
Project Nightjar Online 16/8/13
Our new Project Nightjar site is up and running! The site gives details of our work with egg camouflage, and soon there will be some online camouflage games to play.
South Africa Fieldwork 1/8/13
I'm currently in South Africa with Jared, looking for plover nests to use in our camouflage experiments. Take a look at our twitter feed @ProjectNightjar, and our youTube channel for our latest predation videos.
Here's one of our Chestnut-banded Plover nests getting nabbed by a Pied Crow:
I nearly picked up this boomslang as i was clearing fallen branches from the track!
Photos of Zambian nightjars & coursers added to my photography page. Here''s a close-up of a fiery-necked nightjar (Caprimulgus pectoralis)
Bush fire at the Bruce-Millers':
Now I'm back in Zambia doing more fieldwork. This is the beautiful jacaranda avenue at the Bruce-Miller's farm:
I've been adding some photos of the things I've spotted in South Africa to my photos page:
