Chick-time. Long night, we tagged some interesting #nightjars and ringed the chicks of five nests. These birds hatched last week. Interesting size and color difference on one nest; age difference 3 days (usually one).

Tonight I visited the Belgian coast while other members worked in our sites in Limburg. Goal: tag the most western #nightjar of the country 🇧🇪. To our biggest surprise, we captured not one but TWO males 🥳. @MaartenDeRijcke

PARASITES! #nightjar, #nematode and #biology community, we need your opinion. Does anyone recognise these parasites on the inside of this nightjar skull? How can they get infected with it? Via insects? 🐞

Busy night at the former airfield of #malle. Captured 14 birds, including 4 recaptured. Also found three predated nests. #nightjar

Productive night. Found three new nests, captured eight #nightjar and downloaded some activity data from a long-term logger.

SECOND ROUND! Project deadlines = less fieldwork, luckily I could join the team yesterday. They found 8 new nests. Most with recently laid eggs 8. Some nests only 7m apart! Also recaptured some old friends! #nightjar Thomas Veryser

IT FINALLY HAPPENED!! After 15 years of studying #nightjar, and finding more than 400 nests, one of our team members Richard Schnürmacher found a three-egg nest! Fingers crossed it does not get predated or disturbed!

Last week I had the opportunity to join a team of UAntwerpen out in the field, on a queste looking for nightjars! Three very intensive days delivered promising results. Looking forward to help out more this season & coming seasons. Ruben Evens

Het vermoeden dat het om een onbeschreven soort gaat, is er sinds jaren '90. Ik hoorde de zang van deze soort op Timor reeds in 1995 maar veronderstelde dat het ging om de Large-tailed Nightjar. Intussen is duidelijk dat de territoriale zang van deze soort erg verschillend is.

DONE. Captured more than 400 #nightjar, found more than 50 nests. Nearly 56 gps/acc deployments. We traditionally wrap up in September, but juveniles did not start #migration yet?Should we try again next week 👀… @UCLouvain_be UAntwerpen Natuur en Bos FWO

Headphones on, volume to max. #Nightjar chugging song ending (which suggests paired) at quarter speed. Calls as 2nd approaches, then wing claps (2 birds) & more calls as lead male flies off to right. Paul Baxter The SOC BTO Scotland Greg Conway Ruben Evens British Birds

FIVE DAYS LEFT to the abstract deadline. Not just nightjars, but anything related. Not just academics, but everyone involved in nightjar research. We will have lots of discussion sessions, so please send us ideas for these, too. We'd love to hear from you!
