Ispol'zuya razlichnye ekologicheskie nishi v zone sovmestnogo gnezdovaniya, vidy realizuyut potentsial k rostu chislennosti populyatsiy, chto pokazyvayut issledovaniya v basseyne r. Indigirka. Sterkh zdes' obitaet na nizkikh, obvodnennykh uchastkakh tundry vblizi krupnykh ozer, kanadskiy zhuravl' chashche vstrechaetsya na bolee vysokikh i sukhikh uchastkakh. No issledovaniya v basseyne r.
