Best Zoom lense for wildlife

[MrsSmith0817]

Hello, 

My husband got me the EOS R10 for Christmas and since I'm relatively new at photography with a camera I was wondering if anyone could suggest a zoom lense under 5 grand that I would be happy with. The lense I currently have is 18- 150 and if the wildlife isn't right there in front of me, you can't really see any details! My phones 3 lenses takes a better picture if I'm honest!

Thank you!

Nice grab of the Waxwing, big fan of the composition and with the berry in it's mouth.

Thanks, I don't see waxwings very often, but when they do there are lots of them, but hard to get a good shot in that holly tree.  That one happened to be visible and when it posed with the berry, and I got lucky.  The waxwings and a few bluebirds cleaned out the tree in a few days.
