A kind of birdcage can close off the door-plate of the openings such as this, the Sheng plate that Ji Yishen sets in the what elongated space, and can extract out along the extending direction in the elongated space comprising one with opening around the shell in an elongated space with two openings out, two. Wherein, the elongated space is horizontally extending, and the Sheng plate can stand in the case where extracting the elongated space out for birds, and the movement by the Sheng plate to be pushed into the elongated space, make the birds bend body to bow and accommodate in the what elongated space, the effect of thereby reaching and the large birds accommodated with a lower height of birdcage, and damaging its feather during accommodating.一種鳥籠，包含一圍繞出一具有二開口之長型空間的外殼、二可開啟地分別封閉該等開口的門板，及一伸置於該長型空間中，並可沿該長型空間之延伸方向抽出的盛板。其中，該長型空間是沿水平方向延伸，而該盛板能在抽出該長型空間的情況下供鳥類站立，並藉由將該盛板推入該長型空間的動作，使所述的鳥類屈身低頭而容置於該長型空間中，藉此達到以高度較低的鳥籠容置大型鳥類，且不使其羽毛在容置過程中損傷的功效。
