Disappearance of Indian house crows from Kerala

I was showing my 4-year-old daughter different birds when I realized she has never seen an Indian House Crow. Growing up in this village, House Crows were everywhere, while Jungle Crows were a rare sight. Now, it’s the opposite—Jungle Crows are common, but I haven’t seen a House Crow in years here in Kerala. Does anyone know what might have happened to them?
