BirdNote Daily The Early Bird
4 snips
Jan 20, 2026 Birds have a fascinating strategy when it comes to feeding. Dominant species stay lean during the day, only to feast later, which helps them avoid predators and cope with cold nights. On the other hand, subordinate birds must gather food whenever possible, leading to a heavier build as a survival tactic. Surprisingly, eating later might even boost longevity for woodland birds, challenging the old saying about the early bird. Tune in for insights that flip conventional wisdom on its head!

Episode notes
Lean Strategy Boosts Survival
- Dominant woodland birds stay lean during the day and fuel up later when it matters most.
- Staying lean improves agility to avoid predators and they metabolize fat at night to avoid hypothermia.
Fat As An Insurance Policy
- Subordinate birds carry fat because they must eat whenever and wherever food appears.
- This fat hedge compensates for unpredictable rations but reduces agility against predators.
Fat, Nighttime Metabolism, And Cold
- Birds metabolize fat at night to avoid hypothermia, linking body reserves to temperature regulation.
- Dominant birds choose feeding times to balance energy needs and predator avoidance.
