This rare video shows a female cowbird killing live warbler nestlings to make way for her own egg! Brown-headed cowbirds are one of the few species in world that never take care of their own young. Instead they lay their eggs in other birds nests and rely on the foster care of other species to raise their babies for them. Recent experiments confirm that brown-headed cowbirds "farm" their hosts โ�� the act of removing other removing other bird's eggs from their nests so they can create opportunities for themselves to lay their eggs in that nest. This strategy not only makes room for cowbird eggs but also resets the biological clock of the host species to lay new eggs and raise the cowbird baby alongside its own! And cowbirds may have an even more dastardly trick up their sleevesโ��for more check out www.pbs.org/nova/sciencenow/ Video Credit: Phillip Elliot, Eastern Connecticut State University

Strange fungi Nidulariaceae

The Nidulariaceae are a family of fungi in the order Nidulariales. Commonly known as the bird's nest fungi, their fruiting bodies resemble tiny egg-filled birds' nests complete with tiny "eggs". As they are saprobic, feeding on decomposing organic matter, they are often seen growing on decaying wood and in soils enriched with wood chips or bark mulch; they have a widespread distribution in most ecological regions. The five genera within the family, namely, Crucibulum, Cyathus Mycocalia, Nidula, and Nidularia, are distinguished from each other by differences in morphology and peridiole structure; more recently, phylogenetic analysis and comparison of DNA sequences is guiding new decisions in the taxonomic organization of this family.
