Low Survival Rate of Fledglings

It may surprise you to discover that fledgling hummingbirds have a very low survival rate. Just how low? Well, a startlingly low percentage, up to three-quarters of a given year’s fledglings are likely to die. The causes of this include predators, disease, accident, problems which occur during migration, or other problems.

As a hummingbird enthusiast myself, I am astounded by the sheer number of fledglings that are likely to die each year! What about those of you reading this post? Because a large number of fledglings die each year, I am even more appreciative of those that do survive. While I always have thought of hummingbirds as beautiful and remarkable creatures,I will never again take their survival and presence for granted.
