Hen Harrier Susie, whose chicks were stamped to death on a Yorkshire Dales grouse moor in 2022, has been found dead on a N Pennines grouse moor with gunshot injuries.

18+ months of silence about this crime from the police & Natural England.

If ever there was an example demonstrating the high level of persecution faced by Hen Harriers on UK grouse moors, the lack of consequences for the offenders, and the lack of justice for the victim…

NEW PAPER: Parental anti-predator investment in red kites shifts with food conditions, reflecting both offspring vulnerability and reproductive value, with their relative importance changing across nestling age.

Was super excited to present our global analysis of raptor🦉🦅 mortality, effects of spec traits and Human footprint @eounion.bsky.social #EOU2025 in Bangor this week. Attended so many interesting talks and I'm thankful to all the new friends and connections made in the bird world :) #RaptorResearch

We had a surprise visitor - a Eurasian Eagle owl (Bubo bubo) during one of our behavioural experiments with Tawny owls!
In the spectrogram, you see the resident Tawny and the Eagle owl calling during the same time!

Looking for your first quantitative ecology post-doc? Then get in touch.

I will be co-supervising a post-doc with Lourens Swanepoel (based in SA: @Univenofficial). You will have access to many awesome data sets and the focus will be on applying hierarchical models.

This spring, we're collecting data for the 2nd year, looking at how territory quality influences aggression in Tawny owls in South Bohemia. Observing owls with a thermal scope changes the game and lets us capture really cool moments of individuals and pairs during the night🦉🤩 #RaptorResearch #Birds

We hear lots of news about golden eagle mortality by wind turbines. However, this is not the largest source of mortality in the western US. Any guesses?

Illegal shooting... Needless and disgusting! (Katzner et al. 2020, Millsap et al. 2022)

Raptor Poisoning in Europe Between 1996 and 2016: A Continental Assessment of the Most Affected Species and the Most Used Poisons | doi.org/10.3356/jrr2373 | Journal of Raptor Research | #ornithology #RaptorResearch 🪶
Raptor Poisoning in Europe between 1996 and 2016: A Continental Assessment of the Most Affected Species and the Most Used Poisons
La exposición a los pesticidas es una de las amenazas de mayor alcance para las aves rapaces. Recopilamos datos sobre envenenamiento de aves rapaces en 22 países europeos, abarcando 3196 incidentes de envenenamiento reportados que afectaron a 4437 aves rapaces envenenadas de 37 especies entre 1996 y 2016. Las aves rapaces más comúnmente envenenadas fueron carroñeras obligadas o facultativas, pero su contribución proporcional al número total de rapaces envenenadas varió de un país a otro. Los ratoneros, las águilas, los buitres y los milanos juntos representaron el 85% de las aves rapaces envenenadas. Sobre un total de 4437 aves rapaces, Buteo buteo (46%), Gyps fulvus; (12%), Haliaeetus albicilla (9%), Milvus milvus (7%) y Circus aeruginosus (5%) fueron las más frecuentemente afectadas por los pesticidas. De las especies documentadas, seis están amenazadas a nivel mundial y 15 están disminuyendo a nivel mundial según la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza. En total, se detectaron 41 pesticidas de forma independiente, y 34 pesticidas combinados. Se notificaron carbofuranos y aldicarb en el 55% y el 14%, respectivamente, de las aves rapaces envenenadas con detección de una sola sustancia, y en el 57% y el 18% de las aves rapaces envenenadas con múltiples sustancias. Más de la mitad de las aves rapaces envenenadas con carbofurano y aldicarb se reportaron después de las prohibiciones comerciales de estas sustancias. El carbofurano fue el veneno más comúnmente detectado en cuatro grupos de aves rapaces con diferentes dietas. De 1589 aves rapaces envenenadas con carbofurano como sustancia única, el 88% fueron categorizadas como carroñeras facultativas. Los casos de envenenamiento con fechas conocidas alcanzaron su punto máximo en marzo–abril, con el 37% de las 3566 aves rapaces envenenadas durante este tiempo. El envenenamiento de carroñeros facultativos alcanzó su punto máximo en marzo–abril, mientras que la estacionalidad del envenenamiento en otras rapaces estuvo menos claramente definido. Concluimos que el uso generalizado de plaguicidas que afectan a las aves rapaces en Europa y la gama asociada de especies afectadas sugieren que pueden haber implicaciones para la reducción de los servicios ecosistémicos que estas aves proveen.
