Cliff swallows and the extended phenotype

            Some birds prefer to build nests in trees or simply nest in tree cavities. One species, in particular, prefers to build a nest out of mud on the side of an outhouse. Searching along the banks of a river for mud may sound like a dirty job. However, if... Continue Reading →

Changing heron behavior?

By Lindstedt and Gazaille Last fall, we began a research project that involved studying the behavior of the Great Blue Heron and it’s nesting habitat. We have made several trips to what is known as “Heron Island” on Lake Norman. Our first objective was to record baseline data, which included counting the nests in each... Continue Reading →

Bird diversity

Too Much Disturbance

It is too early to know for sure, but there is a good chance that the great horned owl pair may soon abandon the nest that they have used for the past four years. What is most troubling is the fact that there are already eggs (maybe chicks) in the nest. We were hopeful for... Continue Reading →
