Greetings, We are interested in individually marking a large number of gulls (1000?), and I am brainstorming trapping techniques (we would be trapping at a colony and/or a landfill) and the best way to color mark them so that they can be easily seen from a distance. We are considering pitagial tags, but there might be other options out there. Thanks! Danielle
