New work from @devisatarkar.bsky.social et al on how effects of climate variability- particularly more unusual events - depend on developmental stage & prevailing conditions in Wytham Woods great tits.

New preprint! 🪶

We analysed 60 years of data on 83,000+ great tits to show how extreme climate impacts on nestling growth and survival are stage-specific and context-dependent 🐣 🌍🔥❄️

The paper shows that the problem is strongest for ‘short’ duration lists so suggests some possible correction possible.

Yes, very much a potential issue, I think. Standardised, randomly allocated, transects/counts seems the best way round this, but even here can be potential bias, as a former PhD student of mine @wenyuanzhang.com showed here. But the first step is to quantify the biases

Habitat change and biased sampling influence estimation of diversity trends
Zhang et al. demonstrate that data gaps in longitudinal bird surveys are often associated with habitat changes. While habitat changes affect biodiversity trends, they can lead to failure to record bio...

They show that this is plausibly explained by observations of rare (or otherwise appealing) species leading to a greater probability of initiating a list

Large citizen science datasets are powerful tools for biodiversity science, but they may have biases. Nice new paper from @louisbackstrom.bsky.social et al. showing that for eBird and Birdtrack lists there is a tendency for rare species to be over-represented

I first visited Fair Isle in 1986 as a seventeen-year-old, benefitting from a Richard Richardson bursary to cover the accommodation costs at the bird observatory. As an inexperienced inland birder,…

One of the most incredible WTF!! moments I have witnessed in 41 years birding Belvide. 8 White-rumped Sandpiper on the north shore between 4pm-5.30pm. Just short of a British Record of 11 on the outer Hebrides. Thought I'd lost the plot when I saw them. Still pinching myself. #UKbirding

Out @animalecology.bsky.social today - a paper with David Ewing in which we explore the #HPAI outbreak in the terns. We find bird-to-bird transmission to be the main driver of infection and estimate the probability of mortality to drop from 0.26 to 0.14 from 2022 to 2023: doi.org/10.1111/1365...

Pushing the limits of record shots, but good to see this Black-necked Grebe that had appeared at Farmoor this morning still there at sunset today - one of those only just annual species I thought I'd missed locally this year. Interesting to see it sticking close to the gull roost - natal memories?
