Ordered that the orders are affirmed, without costs or disbursements.
The Family Court properly terminated the mother's and the father's parental rights upon the ground of permanent neglect ( see Social Services Law § 384-b [a]). For a continuous period of 17 months following the children's placement into foster care, the mother and the father failed to plan for the children's return despite the diligent efforts of the petitioner mercyFirst to strengthen and encourage the parental relationship ( see Matter of Nathaniel T., 67 NY2d 838, 840; Matter of Tynell S., 43 AD3d 1171; Matter of Darlene L., 38 AD3d 552; Social Services Law § 384-b [a], [c]). The court properly committed the children to the care and custody of mercyFirst and the Commissioner of Social Services of the City of New York for the purpose of adoption ( see Matter of Evelyn Moncrieff G., 42 AD3d 568; Matter of Vincent Anthony C., 235 AD2d 283).
The mother's and the father's remaining contentions are without merit.
