First State of Nature for Yorkshire published today! @_BTO very proud to be a contributing partner, thanks to data on birds, plants and other wildlife collected by dedicated volunteers in Yorkshire @_BBS (https://t.co/6V5fOLa1hD)
And evidence that declines in woodland birds that nest close to the ground are most severe where deer are most prevalent: through impact on vegetation (cover for nesting and where they forage) is greatest
@RichDGregory3@RSPBScience@Natures_Voice Multiple and varied causes of woodland bird declines - mostly climate change, deer browsing, woodland habitat deterioration; migrant woodland species also impacted by conditions in Africa and on route, chaffinch recently by trichomoniasis - but all very worrying @_BTO@BBS_birds
Great that we're able to produce a wintering waterbird indicator again after a year's hiatus due to missing data from the 2020/21 winter because of covid effects on coverage. Still going down :-( a combination of underlying population changes and winter range shifts @WeBS_UK
@pboesu@_BTO feeling embarrassed by my lack of non-native expertise but what kind of parrot is that? Closest I could find was Orange-chinned but without a red eye-ring..๐
A massive contribution to BTO in many different areas over the last 30 years (and we forgot to mention DEMON ๐earlier today) and lovely guy to boot. The stories of his - many - mishaps and wardrobe malfunctions are now the stuff of legend in our organisation!
Good to see this out, declines in farmland birds are depressingly similar to those across the UK and Greenfinch still hit badly by disease, but interesting to see Starling numbers in NI apparently holding their own.. @BBS_birds
Trend patterns for a well known and some less known non-native bird species in the UK, thanks to efforts of volunteers in the @WeBS_UK These are wintering trends but these species are basically resident in UK so broadly reflects breeding populations too @_BTO#INNSweek
Very happy to see our paper, led by Stanislas Rigal
@isemevol coming out in @PNASNews
https://t.co/OT33FrlgmGโฆ | Shows power of European citizen science covering 28 countries, 37 years, 170 bird species and 20,000 sites including @BBS_birds volunteers
Lovely ๐ brings back memories of working on murrelets & auklets in the Queen Charlotte Islands, never found one of these on its nest though #seabirds
@m_livesey @woodlandbirder @ukrbbp@RSPBScience@_BTO Model has full site and year effects and run on whole time series to make best use of site info (some sites monitored every year for >25y), the 5-yr smoothed trend extracted from outputs & formally tested. Data from every year used & we use counts but rarely > 1 or 2 for LSW
Applications still open for under 18s for this summer's BTO Bird Camps in all four UK countries, they're free and have proved very popular in the past, more details here (https://t.co/Ddu3gzsxLe) https://t.co/mcvi6q0dU2)
