Puffins and Shags seem to have been hit hardest by recent storms, with many reports of birds washed ashore. This includes one Isle of May Puffin that was ringed as an adult in 1995, making it at least 34 years old!

How much temperate rainforest could there be in the UK and Ireland, and where? Despite campaigns calling for restoration in both countries, these questions have been difficult to answer. In our new paper we assess the evidence base ๐ŸŒ๐Ÿงช๐ŸŒ๐ŸŒณ๐ŸŒฒ 1/9

Our 9โ€‘year study across an urbanโ€“rural gradient shows native trees, especially oaks, boost blue tit breeding success. More native foliage supports more of the birds preferred prey and improves reproductive success.

Ocean warming threatens seabirds in the North Atlantic Climate change is causing ocean warming, acidification and loss of sea ice. This, in turn, is leading to shifting biogeographic distribution and in some cases species extinction.

Figure with two panels. Left panel: visualisation of a 3D movement track. Right panel: visualisation of the 3D direction of movement as two angles (one horizontal angle and one vertical angle).

We have a preprint about modelling three-dimensional movement tracks, led by @njklappstein.bsky.social.

The model takes the form of a step selection function and, just like in 2D, it can include directional persistence, attraction to targets, and habitat selection.
