媒体文件注释
1 adult m, who for awhile was perched next to what appears to be a 2nd-year m (black crescent on breast appeared smaller). They were posturing as if territorial challenging, but not emphatically or particularly aggressively. A brood was raise in this same are last summer. The full adult m was also doing long call territorial calling from same tree as last year's brood.
观察细节
two m, posturing/dueling on a sapling. Just prior, one of them appeared to be claiming the territory (via repeated long calls from stationary position) on and nearby the tree with nest cavity that had raised a successful brood last year. The other m looked like it was a 2nd year bird (an product of that brood)?
