‘England’s Military Heartland’ is a unique, insightful, in-depth inquiry into how war ideology, preparation and practice has insinuated itself into the narrative of Salisbury Plain, writes @nicolawriting.bsky.social www.caughtbytheriver.net/2025/10/engl...

That has always been the case, also an ageing birder cohort.

Generally speaking little evidence for unassisted eastward vagrancy in landbirds across the Atlantic (due to prevailing winds), although clearly some things make it from Iceland e.g. Redwings where conditions more likely to be condusive. Bermuda a good case in point.

Birders do miss things for the reason you state.... and this is when lots of folks are looking for a specific bird. So much cover on Scillies now and an order of magnitude fewer birders than the 80s peak.

Intensifying grassland management leads to massive loss of arthropod species. However, total arthropod numbers remain more or less stable. Many losers, few winners. doi.org/10.1016/j.bi...

Would assume that at least 10 times that number of birders there at the moment....

Sure, but how many other (much less conspicuous) birds aren't visible from a public right of way most of the time and on Tresco/Mary's....

Indicative of what proportion of birds are missed on Scillies that a pigeon could basically evade detection in the 1.48 km2 of St Agnes despite lots of people looking #UKBirding

Heritage = heritable there. Was saying that there isn't evidence that there is genetically-controlled prey-specialisation in generalist raptors
