Bird bones from the Late Pleistocene (31-24 kyr) Ikhine-2 site (Central Yakutia), one of the key Upper Paleolithic sites in northeastern Siberia, have first been studied. This is the northernmost and the oldest bird association in the Pleistocene of Eastern Siberia. Among the bone materials available, the coracoids of the extinct Dyuktai goose (Anser djuktaiensis) and the hooded crane (Grus monacha) are of particular interest. Dyuktai goose is a large representative of the mammoth fauna, originally described from younger deposits (12-13 kyr) in southeastern Yakutia. This is the second find of this species in Russia, which significantly expands our understanding of the geography and time of its distribution. The hooded crane, a rare modern species with a limited habitat area, has first been found in paleontological record. This find indicates the northern distribution of this species during the Late Pleistocene Karginian interstadial. Bones of Anas crecca and Larus canus have also been found at the site.
来自西伯利亚东北部关键旧石器时代晚期遗址之一的伊赫涅-2 地点（雅库特中部）的晚更新世（31-24 千年前）鸟类骨骼，首次得到了研究。这是西伯利亚东部更新世最北部和最古老的鸟类组合。在现有的骨骼材料中，灭绝的 Dyuktai 鹅（Anser djuktaiensis）和冠鹤（Grus monacha）的肩胛骨特别有趣。Dyuktai 鹅是猛犸象动物群的大型代表，最初是在雅库特东南部较年轻的沉积物（12-13 千年前）中描述的。这是在俄罗斯发现的该物种的第二个标本，大大扩展了我们对其分布范围和时间的了解。冠鹤是一种栖息地有限的稀有现代物种，首次在古生物学记录中发现。这一发现表明，该物种在更新世晚期的 Karginian 间冰期分布于北部。在该地点还发现了斑嘴鸭和银鸥的骨骼。
