I use a pre-made sugar solution sold in a bird store for hummers. (not that red powder) You mix it with water. I only feed the hummers in the fall. I don't see many in the spring. We have mostly Broadtails and you can hear the males. I haven't heard very many. Used to have loads of them in the foothills.
I get 3 varieties of doves. Eurasian Collared (pests) White Winged, and Mourning. The Collared and the White Winged hang around in the winter.
The Juncos, White Crowned Sparrows and the Towhee have learned to use the flat feeder on a post. We had to put it out of the squirrel's and deer's reach.
