One for the occasional series of #ornithology papers you need in your life but might not have read - Common/Spotted Sandpiper flight style as an antipredator behaviour.

Solanum revealed 2 species: nigrum & nitidibaccatum, Black & Green Nightshade. Apart from the obvious berry colour, it always remained possible that Green Nightshade could have been unripe berries.
Green= sepal lobes expand as the berries mature
Black= stays the same

Can species reintroductions harm biodiversity rather than help it? Are we using reintroductions as a distraction from the real drivers of our nature crisis? Listen to my conversation with the one and only @alexanderlees.bsky.social 🌍🦤🧪🪶

A middle-aged man with a bald head sits in front of bookshelves filled with scientific and academic texts in what appears to be a home office or study. He's wearing a dark grey jumper and has a slight smile whilst looking directly at the camera.

How to find Mogulones crucifer:
The weevil is native to Europe/West Asia, but has been introduced to North America to control its host (Cynoglossum officinale; Hound's Tongue) which is invasive there.

If you want to identify, well, anything, I recommend this post from @weevil-see.bsky.social. His choice of weevils to illustrate it is of course excellent, but it applies to everything from mushrooms to marsupials. This is how you can be a good identifier of things.

I started a blog and my first post is online!
The posts will try to explore topics which are not typically covered by introductory literature and textbooks, e.g. because they are considered to be "too basic". Let me know what you think!

Species Identifications: Common Pitfalls
Some thoughts about Identifications. How do we identify properly? How do we avoid mistakes?

Thought I'd post something about separating Nysius senecionis and graminicola, as both are now widespread. The features to focus on are the extent of the matt field of the evaporatory area (the brown bit) and the length of the 1st hind tarsal segment relative to the 2nd and 3rd.

At #EOU2025 @eounion.bsky.social conference next week, we'll show new evidence implicating forestry in declines of British Marsh Tits during the era of woodland conversion in 1950/60s-1980s.
This was period of steepest decline in Marsh Tits. Why? What was going on back then? #ornithology 1/5

NEW! The latest UKCEH Land Cover Map, describing the UK land surface in 2024, is now available 🏞️ 🌳

See what broad habitats—ranging from broadleaved woodland and arable land to freshwater and urban areas— there are and where in England, Wales, Scotland and Northern Ireland.

Also, white stork is doing very well on the continent (partly due to reintroductions), see fe breeding trend in the Netherlands ((c) @sovonvogels.bsky.social ). No doubt this population outbreak will spread to the UK. Better to use limited funding for conservation to species that really need it.

Most weevils have a snout, elbowed antennae & a heart-shaped foot—making them easy to recognise (with a few exceptions). 🪲

Absolutely incredible turnout for Budapest Pride! So proud of all the organizers, including some old friends, who estimate hundreds of thousands— major embarrassment to Orban

Yes, it is another Philopedon plagiatum.

Since we are still talking about interactions, I worked with some ecologists a couple of years ago on measurement scale, interactions and interpretation issues. I think some problems arise from failure to distinguish prediction from inference, a chronic problem in ecology imo doi.org/10.1111/brv....
Three common inferential errors when investigating context dependence in ecology. Consider a test of context dependence in its most basic form: a 2 × 2 factorial experiment, measuring an ecological response Y, to the crossing of factors X and Z, each with two levels. The analyst fits a statistical model with an interaction term to the data: Y ~ X + Z + X × Z, to test for and quantify context dependence. Three inferential errors are possible when the measurement scale or symmetry of the interaction are overlooked: detection and magnitude (Type D), sign (Type S) and misidentification of underlying processes (Type A).

Every year, fewer #WhiteStorks cross the Straits of Gibraltar on their annual migratory journey. In this paper, we unveil the mechanisms driving the recent and rapid loss of their migratory behaviour.
