Want to Help Nesting Birds? Avoid Offering This As Nesting Material.

While it seems helpful to offer dryer lint to nest-building birds, it is not a suitable material for the job. First, the strands of dryer lint are too short to be woven strongly. Nests built with it can develop holes, sag, or even collapse because they lack tensile strength. Furthermore, lint from fabric is more absorbent than naturally occurring materials such as twigs, dried grasses, moss, or feathers. While dryer lint seems like it would make a soft lining suitable for newly hatched birds, it readily absorbs moisture, which isn't helpful at all in trying to keep nestlings warm and dry.

  • Re: How do Birds Keep Warm in Cold Winter Weather?
    I understand that the ducks' blood vessel arrangement in their feet is to provide the benefits of the counter-current heat exchanger mechanism; returning cold venous blood from the feet is warmed by the descending warm arterial blood, preventing excess heat loss by the feet and avoiding cold blood from chilling the body. This means that the feet are cold, not warm.

    I have the same situation. The feeder is attached to the middle of a large picture window that goes ceiling to floor w/ no ledge or sill for animals to climb or balance. Yet every morning all the sunflower seeds have been cracked open and hulls left. Any ideas what it is?

    I have a bird feeder that sticks to my window and I've been hearing noises against the window at night right now its going on. But whatever it is it is aware of me. And when I get to window it leaves.I can't imagine a squirrel or mouse or possom being able to get at it. ...So as I was reading this article im to assume no bird eats at night. Or no birds will eat at night. Why is that? Then im also thinking of a sinereo that could a lost confused bird eat at night. This eating thing is watching meI turn out the light go there noise dissappears..Thank you.

    I have metal baffles (cones) on my pole for my bird feeders. Something is still tempting them at night. What else could it be? Deer???
