Oxwich Marsh 6 Marsh 2016: the JACSN four

A light to moderate north-westerly wind made for a cold morning.  We put a complicated configuration of five sixty-foot nets in a small area of rushy ground close to one of the large freshwater pools on the marsh as well as a net adjacent to the feeders.

The catch was only 30 birds, and nets were down by 10:00.  It was made up as follows.

The feature of the catch was four jack snipe (we had only caught three in the previous two years) caught at first light.  The nets were in place over an hour prior to dawn and these appear to have been birds dropping in to their day roost.  

We aged the birds on a combination of features including the characteristics of the undertail coverts and shape of the tail feathers.  One was an adult, and the remainder first winter birds.
