Birds absolutely, positively need to be able to fly at a moment's notice

Clearly, without the ability to fly, almost all birds would quickly become extinct. A bird that wants to stay alive does not have the option of 'putting on a little weight'. Birds’ anatomy is designed appropriately. The large flight muscles, anchored onto the breastbone, make up from 30 to 40 percent of a bird’s body weight. Obviously these muscles power the wings, so a bird's body simply can't be too much for the flight muscles.

 

 
 
 
 
Checking out a feeder    Before landing on a feeder that’s not totally familiar to them (like a new one), birds will land on a nearby branch (within about 5 – 8 feet) and watch it for a while. If there’s no branch or perch to land on, the feeder won’t ever be thought of as “safe”.
