Calcium sason is coming up fast; how to get eggshells.ready.

In egg-laying season (coming up real soon!) female birds need extra calcium so their bodies can produce eggs, not robbing their own bodies' of calcium. Sometimes they get extra calcium from eating paint chips (particularly the light colors). Sometimes they get it when you put out egg shells (after making breakfast). Sometimes they get it from the extra calcium added to many types of suet. Some people add very small pieces to bird food, but it's a lot of extra work. If female birds don’t get the extra calcium they need at this time of year, their bodies take it from the birds’ own bones, weakening them.

We’ll save eggshells for the birds; chicken eggs are fine.  We break them into small flakes (no bigger than a dime), rinse, and cook them for about 10 minutes at 350 (to kill bacteria). Or you could microwave them on high for just under a minute. Then we just set them outside on an old plate.


Leave tree stumps for birds         About this time of year, dead trees all over north Texas are in the sights of chainsaws. They may be unsightly, but those dead trees are perfect homes for birds, as they have been for centuries.

Cavity-nesting birds in north Texas (such as woodpeckers, Tufted Titmice, Chickadees, Bluebirds and Wrens) need places to nest. Here’s what we do at our house:

If we cut down a tree, we’ll leave a tall stump, called a “snag” – anywhere between 6 ft. and 20 ft. tall.  This way, the tree is in much less danger of blowing over, and many bird species still have places to build homes. For instance, a family of Red-bellied Woodpeckers is raising little ones, right now, in a snag we “made” last year.

Birds of all species (even a Cooper’s Hawk once) have a perch and can scan from atop the taller snags. Also, we have “posts” on which to fasten birdfeeders and such.
