Hi CoBirders,

I posted here a couple of times earlier this season to invite new volunteers to adopt a survey route for the North American Breeding Bird Survey (BBS). The survey season is just a month away, and it is not too late to get involved. Colorado hosts 136 BBS survey routes distributed all across the state. There are currently just eight Colorado routes are open for a new volunteer surveyor (see list below). Five of these are on the Eastern Plains, where our grassland bird populations are undergoing notable declines. It would be wonderful to have more of these routes surveyed to help provide info on population changes there. And there are three routes in south-central Colorado needing coverage. 

Requirements for participation are: (1) access to transportation to complete a survey, (2) good hearing and eyesight, and (3) the ability to identify the breeding birds in the area by sight and sound. Knowledge of bird songs and calls is extremely important, because most birds counted on the surveys are detected by sound. A BBS survey requires about five hours to complete, plus travel to and from the route location.

Can you volunteer to adopt a survey route? Contact me directly if you are interested in a route or have questions.
