The ringing started at Tirat Zvi's Water-Tower, back in 1973, with the initiative of Ofer Shimoni. He brought Shalom Zo-Aretz, and both a chick and a mature bird were ringed, according to the registry at the ringing center. Then there was an intermission, until this veteran nesting came to my attention (Meir Ariel).
Starting 2002, there was a continuum of bird-ringing, with a touching story, where the mother kept to herself at the feeding period, and the chicks where removed from the nest, to be taken care of by live-stock women. The was a total of 31 bird-ringing, including 2 adults, the last was a female last year (2009), which was rang by Shauli Aviel in Sde Eliyau, a few years prior.
At the Culture House in Nir David, the first ringing was at the season of 1985. A season later only the female was rang, by means of capturing with the help of B.C. Since, I returned to the place only at 1995 with the help of the palm trees people and their crane, and later, we were there at the season of 2007. Then began the first cycle, similar to what we found this year (2010) and the second cycle was rang at the beginning of July.
Last year I was helped by Amir Ezer, and this year, according to the signs we will again have a first cycle, which the chicks were ringed by Motti Charter on they're belly. According to amount of pellets in both places, we can see it is a nest with very long history. According to my experience, if there will be a second cycle, the imposition of the eggs happens at the stage when the chicks of the first cycle are already feathered, but haven't fledged yet. The mother broods at their side, a situation I've seen at the past in the boxes.
