Window mounted hummingbird feeders allow you to watch hummingbirds up close from the comfort of indoors. However, some people wonder if these types of feeders are safe for hummingbirds. There are a few factors to consider when using window mounted feeders.
Risk of Window Collisions
One concern with window mounted feeders is that hummingbirds may collide with windows around the feeder. Hummingbirds have very fast reaction times when flying but can become disoriented by reflective surfaces. When they see a feeder up close to a window, they may not realize the window is there and fly directly into it. This can result in injury or even death in some cases.
According to the American Bird Conservancy, up to 1 billion birds die annually in the United States from striking windows. Hummingbirds are particularly vulnerable due to their small size and high speed. One study found that hummingbird feeders mounted less than 3 feet from windows increased the likelihood of collisions.
Tips to Prevent Collisions
If you want to use a window mounted hummingbird feeder, there are some things you can do to try to prevent collisions:
– Place feeders well away from windows – at least 3 feet or more distance is best. This gives hummingbirds more reaction time to avoid glass.
– Install external screens or mesh over window areas by feeders. This physically blocks contact with clear glass.
– Use feeders with built-in “collision guards” that surround the feeding ports and prevent direct window access.
– Apply decals, tape, or other markings to make windows around feeders more visible. Movement and patterns help alert birds.
– Close curtains or blinds on windows near feeders to discourage birds from flying toward the glass.
– Move feeders to new locations regularly so hummingbirds don’t get habituated to flying toward a particular window area.
– Use multiple feeders spread apart to distribute activity and reduce concentrated flight paths near windows.
Other Safety Considerations
Aside from collision risks, a few other factors impact the safety of window mounted hummingbird feeders:
– Leaks – Feeders attached to windows can leak sugary nectar and attract pests like bees, wasps, and ants. This creates a nuisance and health hazard. Use feeders designed not to drip.
– Accessibility – Window locations may limit access for cleaning and refilling feeders. Dirty nectar can grow mold and bacteria. Choose windows that allow for convenient maintenance.
– Predators – Feeders on windows put hummingbirds dangerously close to indoor pets like cats. Make sure pets cannot pounce through open windows and stalk feeders.
– Disturbance – Window feeders may subject hummingbirds to excessive noise and visual disturbance from indoor activities. This can stress the birds. Place feeders on windows away from high traffic areas.
– Climate Control – Windows expose feeders to temperature extremes and direct sunlight which can spoil nectar. Find shaded windows or bring feeders indoors when not in use.
– Escapes – Curious hummingbirds may fly into homes through open windows by feeders. Keep windows shut or use screened feeder cages.
Pros and Cons of Window Mounted Hummingbird Feeders
Below is a summary of the main advantages and disadvantages associated with using window mounted hummingbird feeders:
Potential Pros
– Allows up close hummingbird viewing and photography from inside.
– Can be positioned where convenient for monitoring and refilling.
– Provides shelter from outdoor heat, rain, and wind.
– Keeps nectar fresher by regulating temperature.
– Deters some predators like squirrels and deer.
– Reduces risks of nectar fermenting or becoming contaminated.
Potential Cons
– Increased window collisions and injuries.
– More accessible to indoor pets.
– Requires vigilance to prevent leaks, drips, and escapes.
– Can overheat nectar or grow bacteria if not cleaned regularly.
– May attract insects and spiders on windows.
– Limits hummingbird access when windows are closed.
– Can disturb hummingbird activity with proximity to indoor noises and movements.
Tips for Safe Use
If you choose to use a window mounted hummingbird feeder, some best practices will help minimize risks:
– Place feeder on window with external screen or mesh barrier.
– Apply decals or tape patterns to window areas around feeder.
– Keep feeder at least 3 feet from window edges.
– Refill feeder 1-2 times per week and clean thoroughly.
– Monitor for dead insects or mold in nectar – change nectar immediately if issues noticed.
– Keep cats and other pets away from windows near feeders.
– Select shaded windows and bring feeder indoors when temperatures exceed 85°F.
– Use nectar mixes specially formulated to inhibit mold growth.
– Allow ample flying room around feeder – avoid clustering with other feeders.
– Move feeder to a new window location periodically.
Alternative Feeding Methods
If you decide window mounted feeders are not the right choice for you, there are other good ways to attract hummingbirds:
Pole Mounted Feeders
Pole mounted feeders positioned in gardens or yards provide many of the same benefits without window collision risks. Use a pulley system to lower feeder for easy filling and cleaning.
Tree & Limb Hanging Feeders
Hang feeders from tree branches, hooks, or other supports away from windows. Breaks line of sight between feeders and house.
Deck Rail Mounted Feeders
Deck rail mounts allow convenient access like windows but avoid glass collisions. Keep adequate distance between feeders.
Feeder Trays & Platforms
Ground-level feeders on pedestals or platforms offer easy access while minimizing dangers. Avoid areas where cats roam.
Natural Flower Feeding
Planting native flowers and tube-shaped blooms provides natural nectar sources for hummingbirds. Promotes biodiversity.
| Method | Pros | Cons |
|---|---|---|
| Pole Mounted | – No window collisions – Accessible for refilling – Deters some predators |
– Can be difficult to monitor/photograph – Exposed to outdoor weather – May need pulley system |
| Tree & Limb Hanging | – Natural look – No window risks – Often shaded spots |
– Harder to refill and clean – Access limited by height – Need sturdy support |
| Deck Rail Mounted | – Convenient like windows – No glass collision issue – Near outdoor seating |
– Limited spots on deck railing – Still partially weather exposed – Visible to predators |
| Ground Feeders | – Very accessible – Usually no predator risk – Easy to clean and fill |
– Vulnerable to ants and pests – Need a predator deterrent – Not elevated for best viewing |
| Natural Flowers | – Promotes biodiversity – No equipment needed – Natural feeding behavior |
– No guarantee hummingbirds will visit – Takes time to establish flowers – Access dependent on blooms |
Conclusion
Window mounted hummingbird feeders can allow for convenient feeding and beautiful close viewing opportunities. However, special precautions need to be taken to ensure the safety of hummingbirds around glass. Collisions are a real threat.
If feeders are not positioned an adequate distance from windows or lack collision deterrents, it is best to avoid window mounting. There are safer alternatives that provide many of the same benefits without injury risks to hummingbirds. With careful setup though, window feeders can be an enjoyable way to observe these special birds.
