Very cool info and even better is you got to capture a few photos!@Almi @Horsefeathers Yes those are bands and radio transmitters on the legs. Both are males. It seems that the Eastern population of Whoopers is dominated by males. One bird is the 37 bird hatched in 2007 and the other is the 20 bird hatched in 2013. This information was determined using the bands and photos submitted.
