For the last seven seasons, Barbara Spagnuolo has been coordinating the monitoring of 122 bluebird nest boxes at various parks, open space areas, schools and trails in Castle Rock, Colorado (near Denver). A female Mountain Bluebird using one of their nest boxes, affectionately named “Pink Lady.” For the third time in a row (in the same nest box), this Mountain Bluebird has laid pink eggs. The first clutch of pink eggs was documented last year from her second brood, but this year she laid the pink eggs for the first brood and now the second brood.  The female is healthy and all chicks were healthy and fledged successfully. Fortunately all of her “pink” offspring have been banded and had blood drawn as well (as part of a research project through the University of Colorado), and she is banded as well, so they can track any future activity.

You cannot begin to preserve any species of animal unless you preserve the habitat in which it dwells. Disturb or destroy that habitat and you will exterminate the species as surely as if you had shot it. So conservation means that you have to preserve forest and grassland, river and lake, even the sea itself. This is vital not only for the preservation of animal life generally, but for the future existence of man himself—a point that seems to escape many people.
