When you dig into the biology of birds, there’s no shortage of fascinating facts. Here are a few worth sharing!
1. Bird feet come with an 'auto-clutch' feature
Many people wonder why birds don't fall when they sleep. After all, humans can’t maintain our grip on the remote control when we drift off to dreamland! For us, the act of holding something requires a conscious effort.
It’s different for birds. How it works is there’s a tendon at the back of the leg that pulls tight when a bird rests on a perch. This tightening of the tendon makes their toes curl inward to establish a good, tight grip — even when they’re catching z’s. When the bird “stands” more upright to fly or hop, the tendon releases and “unlocks” the toes.
2. Birds can see magnetic fields
Bird vision is super-fascinating, offering plenty for scientists and birders to dig into. One thing that helps birds map out their great migration journeys is their ability to see magnetic fields. For long-distance fliers, it literally helps them map their journey.
3. Birds have ultra-strong frames
Hollow bones let birds maintain a lighter frame for flying. At the same time, the bone material itself is stronger than it looks. Compared to similarly-sized animals, the bones of a songbird are quite dense, designed to withstand the stresses of flight.
As you can see, the songbirds of the backyard have more going on than you would suspect! Support them with a nutritious snack of sunflower seeds, nuts and fruits found in each bag of Lyric's handcrafted Fruit and Nut Mix.
