'an almost Shakespearean decline'... seems rather revealing of his inflated sense of his own importance.

Reminder of today’s seminar at 3.30
We're all looking forward to this week's seminar, being given by Kristen Ruegg from Colorado State University on the power of avian landscape genomics in the Genoscape Project. Seminar at 3.30pm on Friday 7 Nov in Lecture Theatre 1 in LaMB. Welcome in person or to join online - details ⬇️

Truly the year that keeps on giving!

I've always been tempted by them!

View from my office window in the new @biology.ox.ac.uk building. I didn’t *ask* to be put somewhere with a Rook colony right outside the window but it worked out pretty well 🤓

This video summary (I think a new innovation for the RBBP) is excellent
Our report for 2023 is out now in @britishbirds.bsky.social. There's a summary at rbbp.org.uk/2023-report-... but if you prefer to watch rather than read then here's RBBP secretary @markaeaton.bsky.social with a few key points and some lovely photos! #ornithology #ukbirds youtu.be/arj1m7NfKmY

We are working on the merch...😉 But this artwork is from Kristen's Lab

Quite a masterpiece of economy of information to length there!

This week's EGI seminar - 3.30 on Friday in @biology.ox.ac.uk with Kristen Ruegg on the Bird Genoscape Project. Also live-streamed; details below

Dawn visit to Otmoor this morning rewarded with the elusive Water Pipit that's been around here the last few days in front of screen 1. Never close, light poor, and always looking nervous but a tricky species to see locally these days.

Once a year I like to remind myself and others how amazing Guira Cuckoo eggs are!

Are you sure about the Crossbills? The current AviList checklist has Parrot and Scottish still as distinct (as well as Cassia, Red & Hispaniolan)

More Mapping the UK's Flat Flies Project results published today with Adrian Smith & @sheldonbirds.bsky.social 212 host-parasite interactions, including 70 not previously reported, & a recent switch to gulls by some Louse Flies, Hippoboscidae. @btobirds.bsky.social @dipteristsforum.bsky.social
Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies ...

Reminder of today’s @egioxford.bsky.social seminar from @cornishjackdaws.bsky.social in @biology.ox.ac.uk - will actually be in Lecture Theatre 1
We’re kicking off the year’s EGI seminars this Friday - follow @egioxford.bsky.social for details of these & forthcoming jobs, papers etc
Now that we're properly moved in & set up in the new Life & Mind Building, we're pleased to restart our tradition of Friday afternoon seminar speakers, kicking off with Alex Thornton of @cornishjackdaws.bsky.social at 3.30pm on 31 Oct. Also live streamed: see below for details. Corvid-themed for 🎃

A very close singing Coal Tit yesterday morning - fascinating to see these almost perfectly regular repeated motifs in the song with very rapid changes over huge frequency range. Must require some very precise neuromuscular control of bird's vocal system

Interesting: it immediately ID-d an inland bird (here in Oxford) a couple of weeks ago. We had a wintering one for 3-4 weeks back in 2023; perhaps that is enough to tip the algorithm

Coming up soon (9 am today) an opportunity to hear this classic episode of In Our Time on Bird Migration featuring Tim Guilford of @biology.ox.ac.uk

BBC Radio 4 - In Our Time, Bird Migration
Melvyn Bragg and guests discuss how birds navigate and the risks and benefits of migration

Private Eye nailing it.
If you are in the Oxford area next Thursday, I’m giving a talk on the birds of the Lye Valley area. It’s a multimedia presentation (pictures and calls!) covering the resident and migratory birds recorded in this part of the city. See you there!
