Why Do Bird Feeder Attractants Seem So Fond of Crushed Egg Shells?
Many bird enthusiasts wonder why their feeders attract so many birds when they include crushed eggshells. The answer lies not just in the familiar taste, but in the critical nutritional benefits. Eggshells are an excellent source of calcium, a vital component for many bird species.
The Calcium Hypothesis
Calcium is an essential nutrient for birds, particularly for egg-laying females. Just as pet birds benefit from calcite or cuttlebone to maintain their beak health, wild birds find crushed eggshells to be an accessible and nutritious source of calcium. This is especially important during breeding seasons when females are laying eggs.
Given the health benefits, it is indeed sensible to toast crushed eggshells before adding them to your bird feeder. Toasting not only enhances their palatability but also reduces the risk of microbial contamination. Many commercially available predatory birds or other toxic elements may originate from the rearing procedures of farmed hens, making the cooked shell a safer alternative.
Practical Benefits for Birds
Birds, just like laying hens, can benefit from a regular intake of calcium-rich foods to maintain their overall health. Crushed eggshells provide a natural and convenient source of this vital mineral. Chippies like chickadees, nuthatches, and many small songbirds often consume these shells to strengthen their bones and beaks.
Furthermore, birds will not instinctively protect the eggshells like they do with their eggs. Unlike domestic chickens, wild birds do not guard their eggs. Therefore, there is no need to concern yourself with the birds becoming egg-eating pestilence. It is a safe and beneficial practice for your garden birds to consume crushed eggshells.
