Every spring I get at least 2 odd phylloscs. This presumed Willow Warbler is tiny, brown, and has an odd moult (fresher outer PPs and secondaries than inner primaries, 2 shredded tertials) a hint of a 6th pp emargination & quite an Iberian Chiffchaff adjacent wing formula. 1/2

Ringing has its ups & downs and today we had both... The session got off to a cracking start when we caught our 1st Grasshopper Warbler (out of 2 reeling) at a site where they're now less than annual! But we had to leave shortly after, as a herd of cows broke into the field 🐮

Ever looked at a bar chart and thought “there must be a better way of plotting this data…”? Look no further than sea stack plots!

Most years we catch one to two Green Woodpeckers, so it was great to catch our first for 2024 last week. Even better, this is the first Green Woodpecker we've re-trapped! She was originally ringed by us in September 2023, and was caught in exactly the same net ride!

Most of my #FalklandsShags study colonies are counted from the ground but some are just *too* big. UAVs are useful for photographing big flat colonies, so I can now slowly count our biggest colony, one bird at a time, from the comfort of home. Any guesses on final colony size? 1/

I haven't posted about this cos I'm awful at social media. But I'm proud to say that an idea I've had for a few years now is finally happening.

#ProjectPeewit is go go go.

If you see a Lapwing in Wiltshire in the next few months please let us know.

Wet and windy weather has prevented much ringing recently, so it was great to finally get out and catch migrants on a beautiful spring morning! Highlights included the first willow warblers of the year, as well as a blackcap with a spectacular pollen horn from the continent.

Despite being a ubiquitous feature of UK wetlands, there is still much we don’t know about mallards. I’m a 1st year PhD student at School of Life Sciences, University of Essex aiming to change that by studying mallard survival, productivity & movement 1/6 #BOU2024 #BREAK1

There are 42 Wheatear nestboxes Skokholm Island. Put down in 2019 they’ve been used several times already. Using bespoke camera set-ups we’ve obtained and analysed about 80 hours of revealing footage. However, some are deteriorating so today we built some replacements.

Barometric geolocators are game changers when in comes to tracking small birds! Read our new perspective paper lead by Garrett Rhyne in Ornithology: doi.org/10.1093/ornith… | #ornithology #birdmigrtion | Raphaël Nussbaumer Vogelwarte_Science

Now is an excellent time to read colour rings. Resightings are extremely valuable for monitoring kittiwake population, movement & longevity. Colour ring sightings can be submitted at cr-birding.org/colourprojects or via DM here. All sightings gratefully received

At last, published in Movement Ecology, our paper on Arctic Skua migration! This paper has been about 8 yrs in the making, is the result of a large international collaboration and was a chapter in my PhD thesis. In this multi-colony ... rdcu.be/dCbRS #teamskua 1/9

We invite UK residents from under-represented ethnicities, low-income households, LGBTQIA+ and disabled students to come to Oxford at our expense to find out more about life here as a PhD student. Join us for two days in March and explore the possibilities!! (please retweet)

Our recent paper 'Using citizen science image analysis to measure #seabird phenology’ came from research I presented at the 2022 BOU #CitizenScience conference!

The published results are now available open access here: doi.org/10.1111/ibi.13… 📸🐣
