A keychain set shaped like a birdhouse? There's different colours and versions of it too.

Another option could be fancier or nicer versions of regular stuff like salt & pepper shakers, egg cups, paper towel holders, etc. Brands like Alessi and Koziol have a bunch of that. And you can go for both Design and for funny/quirky versions. Though be aware that you don't gift only tools, especially kitchen or cleaning related stuff. That could be perceived as a comment on traditional roles in the kitchen, etc.
