Yes there is. For example here are all bird observations from La Palma, except yours: https://www.inaturalist.org/observations?place_id=59240&taxon_id=3¬_user_id=opisska
You’ll have to add “not_user_id” to the URL manually, however.
(In general, https://forum.inaturalist.org/t/how-to-use-inaturalists-search-urls-wiki-part-1-of-2/63 helps with questions like this.)
