Birds’ nests are the architectural wonders of the animal kingdom, constructed mostly of plant materials.

In Judith Sumner’s May 1st slide-illustrated lecture at the Arnold Arboretum, beginning at 2:30, we will explore various types of nests and the botanical materials used in their construction. When incorporated into nest structure, stems, leaves, and fibers have anatomical and structural properties that defy harsh weather and rigorous use.

We will also examine the biologically active plant material used to line nests, which may have antibiotic and insecticidal properties. Join us for a fascinating look at nest form and function, with particular attention to plant structures and their adaptive re-use in nest construction. Fee $5 for Arboretum members, $10 for nonmembers.  Register at www.arboretum.harvard.edu or call 617-384-5277. Image from www.unschoolrules.com.
