exchange rate and only make small charges for small payments, the other
PayPal, but their exchange can be less generous, and these payments

Mist net manufacture notes:
The nets are supplied in the usual
3,6,9,12 and 18m lengths (without
net bags). The new supply, have all black loops, so it might be worthwhile
using some white electrical tape
mark the top
loop once you have used the net once. Unfortunately we have experianced
that some of the loops have broken, and this has been caused where the
metal clip on the loops has been crimped snagging the cord making the
odd one or two susceptible
Nets are usually made of Polyester or Nylon. There are various views on the durability of either material, but either is suitable providing their are made of multifilament material and not monofilament. Monofilament nets can cause injury to birds unless the nets are monitored constantly and they are removed qiuckly, as this material is rougher and can cause injury to birds in them more frequently. We will therefore never sell monfilament nets.
Net strengths (thicknesses) used for ringing commonly are 70d (denier), often referred to as super fine, 75d or 110d (standard passerine mesh thickness, with 110d being slightly stronger, but slightly more visible), and 210d, which is usually used for heavier species, but is much more obvious than 70 or 75d material. Basically the higher the denier the slightly more visible the nets will be, but also means they are more durable. There can be a pay off between net life and net visibility. The strength of the net can be increased by using different ply. Net strenghth is measured by multiplying the mesh size by the ply, so for example 70d/2ply has a strength of 140, 75d/3ply the strength is 225, and for 110/2ply is 220. So, a 75d net of 2 ply, with a strength of 150, will be less durable than a 75d 3ply net with s trenght of 225.
Mesh size commonly used for passerine ringing is 15*15 (sometimes referred to as 30mm) or 16*16mm (referred to as 32mm), which is a passerine size mesh, good for the majority of the catches consisting of Warblers or small passerines, with 19*19 mm (38mm) for Thrushes or small waders, and 30*30mm (60mm) for bigger birds such as Owls and Waders, and 45*45 (90) for raptors. Care needs to be taken using large mesh sizes as smaller birds can become more entangled in them. The nets should be more closely supervised and checked more frequently, than you would 14mm, 16mm or 19mm mesh nets.
