Yep. One of the most feeder friendly birds in the Eastern US. Usually one of the first species to find the feeder

It's just right wing projection which is all they ever do. All of their media and social platforms are echo chambers

Why don't I ever see these articles about fox news, oann, 100 different podcasts and YouTube channels, X, truth social, 4chan, etc being echo chambers for the right?

Coarse-grain models can bias seasonal & continental estimates of biodiversity patterns across space and time and grain-related biases intensify during summer & in patchier landscapes, esp. for range-restricted, habitat specialist species at risk of population declines.

Biases were greatest in desert regions with patchier habitat and for range-restricted and habitat-specialist species. Predictions based on coarse-grain models overpredicted avian diversity in the west and underpredicted it in the great plains, prairie pothole region and boreal zones.

Coarse-grain models (even at 3 km) consistently under-predicted range area, potentially missing important habitat. This bias intensified during summer (83%–86% of species) when many birds have smaller ‘operational scales’ via localized home ranges while breeding.

In both seasons, 1 km models more accurately predicted species presence, absence and richness at local sites.

We fit SDMs for summer & winter distributions of 572 bird sp native to US/Canada across five spatial grains 1-50 km using eBird. We combined predictions to generate seasonal biodiversity estimates, validated using observations from 322 well-surveyed sites.

Eg, coarse-grain biases may intensify in patchy landscapes, accumulating to produce misleading estimates of continental/seasonal biodiversity

100s of millions of sparrows and other birds died. In the absence of birds, insects flourished; crops vanished; and as many as 75 million people starved to death. How does that disaster echo in what is happening today, even in the US? Read on: therevelator.org/china-sparro.... #birds

Would love to be included in part 2!

They don't expect to win elections forever. They're very comfortable with the status quo where the opposite party wins every 4 or 8 years as swing voters get bored with whoever is in power, constant power shift which ensures that nothing meaningful ever changes
