Back when we lived in the Occupied Territories of North County, we asked about getting hummingbirds to visit the yard

Folks said put up a feeder and they will find it-- took forever but they finally did

Started out with 1 hummingbird visiting and slowly more started visiting-- I do not know if they imprint on feeding sites but the next year we had more and the year after even more visited

Moved to New Haven and put out a feeder-- never saw a bird for about 2 weeks and then they started showing up and now it is a regular flying circus

Don't know if our experience is standard but it seems they find the feeder-- just a matter of time

They are cool to watch and you find out they have 'vocalizations' as well the hum of the wings-- and they are super aggressive in 'defense' of a feeder once they find it

Maybe some of these other yahoos can chip in with their setups etc or Mac will chime in with a birder's perspective

good luck
