My second DPhil paper is out! A nice example of how continuous long-term monitoring of natural populations can be so valuable for understanding impacts of climate change on wild animals 🪶

Firecrest Chiffchaff

Spring has sprung in Wytham woods today. Chiffchaffs singing (first I've heard here this year), and a surprise firecrest in the mist net.

Great pre-print led by @davididiaquez.bsky.social discussing possible causes of declines in adult and nestling mass. I suggested it be titled "Weapons of mass reduction"

Decline in body mass in adult (left) and nestling great tits. In the nestling plot, the purple line represents all nestling and the green line those that recruited to the population as breeders. Their different slope suggest an increase in the strength of selection on nestling mass something confirmed in the MS by analysing the temporal trends in selection differentials (see link for further information)

We have published a new pre-print showing a decline in great tit adult and nestling mass of around 1 gram in 47 y. [rate of approx. -0.040 Hadanes] With @ellafcole.bsky.social, @devisatarkar.bsky.social, Sam. Crofts, @mcmahok.bsky.social & @sheldonbirds.bsky.social www.biorxiv.org/content/10.6...

New preprint! 🐥🦠🏝️

We study a great speciator, the silvereye, to test whether parasites follow island biogeography rules, and find that parasite diversity and isolation effects depend strongly on transmission strategy.

We are seeking to appoint four full-time field assistants to work on the Wytham Tit Project for 4-8 weeks in spring 2026.
Two 8-week field assistants will join the nest monitoring team; duties for these posts will include (i) collecting standardised data from nest-box breeding populations of blue and great tits, (ii) catching and ringing parent birds, (iii) ringing nestlings, and (iv) inputting data collected in the field. These positions with run from approximately Tuesday 7th April to Monday 1st June. Successful candidates for these positions must have (or be qualified to obtain) a BTO permit to ring adult great tits and blue tits.
A further two field assistants will be hired to support a project collecting behavioural (foraging) data for great tits breeding in the Wytham population. These roles will involve a significant amount of nightwork. Duties will include (i) setting up and calibrating electronic tracking equipment and nest box cameras in the field, (ii) mapping tracking equipment locations using GPS, (iii) helping with catching and ringing parent birds and fitting tracking devices, (iv) assisting with mistnetting to re-trap tagged parents, and (v) inputting data collected in the field. These positions with be approximately 7 and 4 weeks in duration, starting from 13th April and 4th May, respectively. Possession of a BTO ringing permit with misnet endorsement and driving license are highly desirable for these roles.
All fieldwork will take place in Wytham Woods, near Oxford. All Successful candidates must be able to demonstrate skill and enthusiasm for biological research as well as experience of fieldwork under arduous conditions, and both lone work and working as part of a team. Due to the short-term nature of these posts, successsful applicants must already have the right to work in the UK. Salary & Accommodation: Field assistants will be paid at grade 5.2 (£17.37/hour). Contact eleanor.cole@Biology.ox.ac.uk

We are hiring at the Wytham Woods for the upcoming field season. 4 roles available. Please share with anyone who might be interested. #UKbirds #birdringing

New paper published! 🧬🐥🦠

Host WGS data can be repurposed to uncover endoparasite diversity at low cost, without destructive sampling, and outperform 18S metabarcoding. We test it in silvereyes.
