Archiving Nests
Generally it is not a good idea to collect nests; they often contain parasites that may still be in use, are difficult to remove, and can fall apart over time. If you place the nest in an air-tight clear plastic bag, it is startling how many things crawl out from between the leaves and mud. An alternative is to photograph nests, tag them with field collection information, and keep a digital collection that builds over time.
