I keep my greenhouse open all summer because of the intense heat and humidity down here in south Texas. Last week I had a female RT get into my greenhouse and kept hitting her head on the roof. I hung a feeder right in the open doorway and she flew out and hasn't been back since.

There must be something really attracting her in the greenhouse to make her go back in. Something red maybe? Try to find out what it is and maybe move it temporarily.

Good luck!

Yes I too would think they are attracted to something red in the greenhouse. Several times this summer they have flown into my garage, just because of the red thing on the cord.

Bdriver - Sounds like you're doing the right thing. Hope it works this time.
We had to take the red thing off of our garage door cord also. Wish they wouldn't put them there in the first place. Steve - If you haven't already, cut it off and put something else on the end.

It worked. She spent the night and half the next day. Drinking and resting. She had looked frantic and exhausted. Seeing the feeder seemed to comfort her right away. She left the next day. Thanks for the advice about something red. I never thought of that. I'll tell my friend who has the greenhouse.

I used to get hummers in my house all the time when we had the feeder too close to the deck door. THey would fly up into our second story famil room window and try to get out. I would have to get the ladder and wait for them to sit, exhausted, on the window sill. I would put a dish towel over them and take them outside. THey get almost paralyzed when they are tired/scared. I would take them out side, hold them in my hand and they would wake up and fly away. I haven't had any in a while, but I don't miss the drama.
