Eggstraterrestrial Field Work
Intersting piece in The Capital about the work involved in trying to control the invasive mute swan (Cygnus olor) in Maryland. Field workers charged with doing the job must hunt down swan nests, typically navigating through mucky wetlands to do so. Any eggs found are sprayed with an oil that cuts off all air flow through the shells, which prevents the eggs from hatching. Maryland's Department of Natural Resources hopes to target 300 swan nests this year, potentially stopping over a thousand mute swans from joining current populations.
