How sad. Let’s all do our part to help.
3 billion.
North America has lost 3 BILLION birds since 1970.
→ Published in Science (2019) — Rosenberg et al.
→ 29% of all birds GONE in 50 years
→ NOT just rare species — COMMON birds
→ Sparrows: -800 million
→ Warblers: -617 million
→ Blackbirds: -440 million
→ Finches: -240 million
→ Swallows: massive declines (barn swallow -46%)
→ Grassland birds: -700 million (worst hit biome)
The losses are ACROSS habitats:
→ Forests: -1 billion birds
→ Grasslands: -700 million
→ Shores/wetlands: -250 million
→ Desert: declining
→ Only waterfowl and raptors have INCREASED (targeted conservation works)
Why:
→ Habitat loss (especially grasslands converted to agriculture)
→ Cats (1.3-4.0 billion bird kills per year)
→ Window collisions (600 million per year)
→ Pesticides (insect food base collapsing)
→ Light pollution (disrupts migration)
→ Climate change (timing mismatches between food and breeding)
The hopeful part:
→ Waterfowl INCREASED because of targeted conservation (Ducks Unlimited, wetland restoration)
→ Raptors recovered because of DDT ban + legal protection
→ THIS PROVES conservation works — when we actually do it
7 easy things that help:
→ Make windows bird-safe (decals)
→ Keep cats indoors
→ Turn off lights during migration
→ Plant native
→ Avoid pesticides
→ Drink shade-grown coffee
→ Reduce, reuse, recycle
3 billion birds.
That's not a statistic.
That's the sound of your backyard getting quieter.
Every year. 📉
