On February 25, 2018, Dr. Sarah Luttrell will talk about her work on evolution and speciation in the marsh wren (Cistothorus palustris). Dr. Luttrell studies how evolution works by studying subspecies of birds. She will examine how comparing multiple traits like plumage color, size and shape, vocal behavior and genetics in marsh wrens has revealed an exciting pattern of evolution in this bird.
The Annual Migratory Bird Count for Occoquan Bay NWR will be held Saturday, May 12. Jim Waggener leads the count and is looking for volunteers.
Although human use accounts for the greatest loss of our natural landscape in Northern Virginia, deer run a close second in the disappearance of vegetation, not only in natural areas, but in home landscapes as well. (Copied with Permission from Plant NOVA Natives campaign.)
