Is there a zoom lens I can attach to a Kindle Fire for birdwatching?

This is probably pretty pedestrian for you all, but it’s a sincere and slightly desperate question. My 94 year-old mom has been a casual birdwatcher her whole life. She’s still pretty spry but has advanced macular degeneration, with no central vision and can no longer use binoculars/monoculars. Being stuck inside like most of us these days, she gets great joy from watching birds at the winter feeder outside her window, but can’t really see them well and when she approaches they fly away.

I’m looking for a reasonably priced solution and have seen many monoculars with smart phone adapters, but she has a dumb phone and feels she’s too old to upgrade. She does have a Kindle Fire she’s learned to use for a camera and computer. Hence my question about a zoom lens for a Kindle Fire. I’ve seen a few clip on zoom lenses but don’t know if they’d work on a Fire and not sure of their quality.

Or perhaps are there decent wildlife cameras that can link directly via Wifi or Bluetooth without a security camera hub, so it can be viewed with a Kindle Fire?

Any ideas would be appreciated. Thanks.
