THE FEAST IS POISON. 🐦☣️
The storm is over. You fill the feeders to help the birds. You see the birds fighting for a spot. You feel good.
STOP. Check the bottom.
Did snow blow into the feeder ports during the blizzard? If yes, that snow is melting inside the tube right now. Wet grain + Plastic tube + Sun = The Mold Bomb.
Here is the science of "Aspergillosis":
1. The "48-Hour" Rule ⏳ Fungus doesn't need weeks to grow. It needs hours. Wet bird seed (corn and millet) begins to ferment immediately. The mold Aspergillus fumigatus blooms on damp grain. You might not see the fuzz yet, but the Spores are there.
2. The "Air Sac" Trap (Anatomy) 🫁 Birds don't breathe like us. They have a system of Air Sacs that goes deep into their body (even their bones). When a bird cracks a moldy seed, it inhales a cloud of invisible spores. These spores settle in the air sacs and grow into fungal plaques. Result: The bird slowly suffocates while looking perfectly healthy on the outside.
3. The Clump Test 🧱 Go look at your feeder. Shake it. Does the seed flow freely? Or is there a stuck "clump" of seed at the bottom? If it clumps, DUMP IT. That clump is a toxic brick.
⚠️ THE STORM HACK:
The Purge: After any major snow or rain event, empty the feeder completely.
The Bleach: If you see black mold, soak the feeder in a 10% bleach solution. Scrub the ports.
The Scent: If the seed smells sour or musty, throw it away. Fresh seed smells like nothing (or slightly nutty).
Clean food or no food. Those are the only safe options.
📌 Quick FAQ
Q: Can I just scoop out the wet part? A: Risky. 🎲 Spores are microscopic and float upwards. If the bottom is moldy, the whole tube is likely contaminated. Bird seed is cheap; a bird's life is not. Dump it.
Q: What about suet? A: Better. 🥩 Suet (rendered fat) is naturally water-resistant (hydrophobic). It doesn't soak up water like grain does. However, if raw suet gets warm, it goes rancid. In winter, it's usually safe.
Q: Which feeders are safest? A: Mesh or Tray Feeders. Mesh socks (for finches) and open trays allow water to drain and air to circulate, keeping the seed drier. Enclosed plastic tubes are the worst for trapping moisture.
