I have lots of hummingbirds at the feeder but only females.. The number has grown dramatically over the summer, which tells me they are raising young. Where's the male?

They are probably at the bar!! Raising youngsers are hard on the male! I have just started to see a male this week.

I see three at my feeder, how do you tell the difference? The three that I see pretty much look the same except one seems more agressive and keeps the other two away from the feeder. I have considered putting up another feeder.

They are all getting ready to migrate this time of the year, lots of activity as they are filling up for the long trip south. I will have to pay attention tomorrow and see if the males are gone here to, also a Warren County resident. Lace

we have the ruby throated here, red on the neck, the females dont have the red on the necks.

the article above in from South Carolina, so I would think they are getting ready or already leaving NY & NJ areas.

the females of the ruby throat have a blunt tail with the bottom side feathers in white.

do you know the more feeders you put up the more birds you will get?

Had a few a couple of weeks ago, I too am only seeing the females.

The young of most species of birds look like their mothers, initially.
The big increase you're seeing is because of a successful breeding season, with the young in their juvenile (female-like) colors.

Male hummers don't help with the children.

I did not know that. I have 3 on my back deck. I bring 2 in every night or they'll be empty in the morning. It's either the raccoons or the bear. I keep one stuck to the window high so they early ones can still get food before I get up.

I have 8quart feeders that have a large opening that you can get a big scrub brush in to clean them out good. I got them at walmart a couple of years ago for 5.00 I see the same ones other places for 20.00I also got the little plastic cups that go right about the feeder so the ants can't get to the feeder. I got those 4 years ago at walmart and never seen them since any place. I even looked on the internet. Before that my husband made some out of lids from hair spray, etc.

I have 4 that come to my feeder - 2 must be male - 1 has red on his neck - the other has green but not sure if it was his neck or back. I love watching them. They chase each other away from the feeder all the time.

I checked, I still have males here in NW NJ
