Rybachy Trap
The Rybachy trap is a variation or expansion of the Heligoland trap in that it is a large, passive trap consisting of linked funnels terminating in a small chamber from which the birds are extracted for banding and measuring before release. It differs in being larger - it may have an entrance some 30 m wide by 15 m high - and by having a non-rigid body made of netting rather than wire mesh. It was developed in 1957 by Janis Jakšisat under the leadership of Lev Belopolsky at the Rybachy Biological Station (formerly the Rossitten Bird Observatory) at Rybachy, Kaliningrad Oblast in Russia, on the Curonian Spit.

Famous quotes containing the word trap:
“We are not very much to blame for our bad marriages. We live amid hallucinations; and this especial trap is laid to trip our feet with, and all are tripped up first and last. But the mighty Mother who had been so sly with us, as if she felt that she owed us some indemnity, insinuates into the Pandora-box of marriage some deep and serious benefits, and some great joys.”
—Ralph Waldo Emerson (1803–1882)
