Putting a hummingbird feeder on a window is generally considered safe, as long as a few precautions are taken. The main concern with window-mounted feeders is that birds may fly into the window if they don’t see the glass. However, there are several things you can do to minimize this risk.
Use Feeders Designed for Windows
There are many hummingbird feeders specifically designed to be mounted on windows. These feeders typically have some sort of platform or barrier that helps prevent birds from directly hitting the glass. The feeder is mounted on a bracket or suction cups so it sticks out 3-4 inches from the window. This creates a visual cue so hummingbirds can see the feeder and don’t accidentally fly into the window.
Types of Window Feeders
Some common types of window hummingbird feeders include:
- Suction cup feeders – These have suction cups on the back to securely attach to glass windows or doors. The feeder itself sticks out from the window several inches.
- Hook feeders – These have hooks or brackets on the back that allow you to hang them from windowsills or rails. Again, the feeder extends out from the window.
- Platform feeders – These have a wide circular platform that attaches by suction cups or hooks. The feeder sits in the middle of this platform.
All of these designs help prevent window collisions by giving hummingbirds a designated place to feed. The birds don’t have to compete for access to the nectar, reducing aggressive behavior that could cause them to crash into glass.
Place Feeders Correctly
In addition to using an appropriate window-mount feeder, it’s also important to place it correctly. Follow these tips:
- Put it on the outside of the window, not on the indoor side.
- Position it off to the side of the window, not directly in the center.
- Avoid placing it directly in front of vegetation or objects that hummingbirds may try to fly to. Leave some open space around the feeder.
- Mount it on the second story or higher if possible. This prevents other animals like cats from disturbing it.
You may need to experiment with a few different positions to find the best spot. Ideally the feeder should be visible but not directly in the flight path of hummingbirds approaching plants or feeders in your yard.
Use Decals, Tape, or Screens
In addition to the feeder itself, it’s a good idea to put up window markings of some sort. These act as visual cues to prevent crashes:
- Decals – Use bird or hummingbird decals that stick onto the window near the feeder. These make the glass more visible.
- Tape – Put strips of tape on the window in vertical or grid patterns.
- Screens – Add an external screen over the window.
You can also use wind chimes or other noise deterrents. The movement and sound alerts hummingbirds to the window’s presence. Just be sure not to place wind chimes directly next to the feeder, as this may frighten away hummingbirds.
Keep the Window Clean
Make sure to keep the section of window around the feeder clean. Dirt, dust, streaks, rain residue, etc. can cause reflections that birds may fly into. Use a vinegar-water mix or glass cleaner to wash the window before putting up the feeder.
Use Curtains or Blinds
Close any curtains or blinds on the window when the feeder is not in use. This prevents accidental daytime collisions in rooms you don’t use often. Open the blinds when you put the feeder out for the day.
Monitor the Feeder
Check on the hummingbird feeder several times a day, especially at first. Refill it with fresh nectar as needed and watch to see if birds are having any trouble using it. Pay attention for any signs of collisions and reposition the feeder if needed.
Only Use When Home
To be extra safe, only put the feeder on the window when you are home. Take it down at night or anytime you will be away for several hours. This ensures you can supervise and make changes if there are any crashes.
Alternate Location Ideas
If you try a window-mounted feeder and still notice hummingbirds hitting the glass, the safest option is to move the feeder. Some other good placement ideas include:
- Porch or patio roof overhangs
- Tree branches
- Shepherd’s hooks or other types of plant hangers
- Mesh nets or enclosures
- Balconies or railings
Find a spot that allows you to see the feeder from inside but prevents any window collisions. With a little trial and error, you can find the perfect safe place to enjoy hummingbirds up close.
Conclusion
Window-mounted hummingbird feeders can provide an up-close view of these magical birds. However, special precautions need to be taken to ensure the safety of hummingbirds when placing feeders on glass. Using specialized window feeders, decals, and proper placement can allow you to enjoy watching hummingbirds from inside while significantly reducing the risk of injury or death from window collisions.
