If I were you, I would be suspicious of your house keeper's diligence following your instructions. Sounds like your feeders ran empty or got dirty. But bad weather runs my hummers off for a while. They always come back, or others move in to take their place.

Your hummers will be back.

Ditto robs' post. I think your birds are telling on your housekeeper. So sorry this happen to you, especially after all you hard work and caring.

You know I have the same experience as yours, my hummingbird also left its cage and later on came back for after a week or so.

Hummers disappear regularly during the year, for nesting, to move on to greener pastures, to use "better" natural nectar sources that have recently come in bloom, and sometimes--as much as we hate to say it--because they have died. They are wild animals, after all, and highly unpredictable ones at that. Don't blame your housekeeper so quickly!

Rob is absolutely correct--keep fresh feeders out and you will get those hummers back and then some!
