Although not required to show diligent efforts to strengthen the father's relationship with the children because of his failure for some 13 months to keep them apprised of his whereabouts (Social Services Law § 384-b [e] [i]; Matter of Shamell J., 202 AD2d 285, 287), petitioners, nevertheless, did show that as soon as contact was resumed with respondent, they attempted to assist him in dealing with his myriad problems, not least by furnishing residential drug rehabilitation programs to him, but that respondent repeatedly left these programs and relapsed into drug use. Such evidence amply justified the findings of permanent neglect, respondent's participation in treatment programs notwithstanding ( see, Matter of S. Children, 210 AD2d 175, lv denied 85 NY2d 807). Concerning the disposition, while respondent finally began to demonstrate some interest in dealing with his drug and alcohol addictions after the conclusion of the fact-finding hearing, he still had done little or nothing to confront his tendency for domestic violence, unemployment and homelessness. Termination of parental rights is in the best interests of the children, there being no presumption in that regard in favor of a biological parent ( supra), and since only termination will finally "pave the way for adoption and allow the children to grow up in a permanent home" ( Matter of Shamell J., supra, at 288). We have considered respondent's remaining arguments and find them to be without merit.
