Foolishly (now it seems) I have started a HB quest. When I started, there were three gardens, and I knew this was to be a challenge.
But now there are NO gardens.

IF YOU KNOW OF ANY HUMMINGBIRD GARDEN,
WILL YOU PLEASE LET ME KNOW.

I still need to spot five out of seven:

Antillean Crested Hummingbird
Violet Headed Hummingbird
Violet Sabrewing Hummingbird
Saw Billed Hummingbird
Blossomcrown Hummingbird

I have attracted four pairs out of seven. Keeping my fingers crossed

At least you can pause a quest and work on it again at a later date. I think with all the winter stuff, it's going to be difficult to find gardens.

Good luck.
