I'm incredibly excited to share that I've been accepted to give a 12 minute talk about my #PhD work at the International Barcoding of Life #Conference in Thailand this November! If you're interested in #CRISPR, #lateralflow, #invasivespecies &/or #eDNA, I hope to see you there! #IBOL #PhDSky

8 chapters (5 data chapters); 4 field seasons; 20(ish) GPS loggers; 167 GPS deployments; 156 stable isotope feather samples. 2.5 hours of dynamic discussion. No corrections. Ph.Done. 🥹 Thank you everyone who supported me along this wild journey. Beyond stoked. What a way to end #SwiftAwarenessWeek!
Printed PhD thesis. “Movement ecology of a long-distance migratory aerial insectivore at broad and fine spatial scales; tracking Alpine Swift (Tachymarptis melba)”.My examiners, Lesley Lancaster and Rob Robinson, my primary supervisor Thomas Bodey and myself.Viva gifts and decorations from my wonderful friends ❤️

Submitted my PhD. Absolutely stoked. Thank you to everyone who supported me and to those I met along the way. It’s been a journey. And thanks, of course, to these gremlins. Time to crack on with the remaining manuscripts. Bring on the viva!

A raven looking straight into the camera. Due to the lighting, its feathers appear to have a blueish hue. The feathers are well detailed showing the different shales and textures. In its eye you can see the horizon reflected.A close-up of the previous raven picture, focussing on the details of the feathers. The colours show different shades of midnight blue. The top half of the picture has feathers that are pointing downwards, whereas the bottom half has more rounded, overlapping feathers, showing the difference between neck & wing feathers, respectively

Found a random “Garden Birds” book, and this has to be my newest favourite house sparrow fact
An illustrated picture of a house sparrow (brown/grey bird) next to some yellow crocuses (flowers) on a patch of grass. Above the picture is the text “Flower Peckers. House sparrows habitually peck yellow flowers, especially crocuses. No one really knows why they do it.”

Very moving presentation from one of the recipients of the EUEA award from @eseb.bsky.social . As a trans academic myself, seeing effort being put into inclusivity has been refreshing. Thank you for platforming this topic and supporting people like this speaker 🏳️‍⚧️
A picture of a presentation slide which reads "The path to freedom, surviving as a trans academic". To the left is also a banner displaying the logo of the ESEB conference and in front are a few chairs facing the stage. Another presentation slide which contains some Qr code links to resources and some steps which academics could take to make space for trans academics. These steps are as follows: 
- apply for DEI grants 
- support LGBTQ+ scholarship funds
- learn about local medical/legal systems to offer newly-arrived colleagues guidance
- Avoid harmful rhetoric and behaviours
