Hummingbirds are some of the world's, but they face big conservation threats. Because of their tiny size, these birds are often at greater risk than larger birds that may have more ability to adapt. Fortunately, understanding the threats to hummingbirds is the first step to learning how you can help with hummingbird conservation.

Hummingbird Threats

Hummingbirds face both natural and man-made threats, including:

Habitat Loss

While all birds and wildlife suffer from habitat loss, the growth of urbanization, agriculture, logging, and development in tropical areas threatens dozens of hummingbird species. Because these birds are so small and have correspondingly small territorial needs, even minor development can have a tragic impact on rare or endangered hummingbird species.


Not only do pesticides and insecticides eliminate the insects that are an essential food source for hummingbirds, but the concentration of chemicals in the environment can impact these small birds far sooner than larger species. Improper chemical use can easily poison hummingbirds.


Feral cats, as well as outdoor pets, are a major threat to hummingbirds. Because hummingbirds feed repeatedly at the same food sources, a cat can lie in ambush and one swipe of a paw can kill a hummingbird where a larger bird may only be stunned and could still escape and recover.

Window Collisions

Because many hummingbird feeders are placed near windows to provide good views of the feeding birds, window collisions can be common and deadly. Not only can the trauma of an impact hurt or kill a hummingbird, but if the bird's bill is damaged it may not be able to feed properly.

Bad Feeders

Dirty hummingbird feeders can harbor toxic mold that kills hummingbirds, and feeders that leak excessively can attract bees and wasps that will attack hummingbirds. Rancid nectar can also be deadly to hummingbirds.

Poor Weather

Sudden cold weather can be fatal to these small birds, for while the torpor state can help them conserve energy on cool nights, it can be difficult to recover from extreme cold, especially if food sources are scarce. Storms can also destroy food sources, making recovery even more challenging.

Invasive Plants

Invasive plants are often chosen for ornamental value in landscaping but can quickly crowd out native nectar-producing plants essential for hummingbirds to feed. While often beautiful, these new plants are unfamiliar to hummingbirds and do not provide the nectar they require.

10 Ways You Can Help Hummingbirds

Understanding the risks hummingbirds face can help birders learn how to help these flying jewels. To give a helping hand to hummingbirds:

  1. Support habitat conservation through donations to appropriate organizations, and choose tropical products such as shade-grown coffee and chocolate that are produced with conservation in mind.
  2. Minimize pesticide use on your landscaping and garden, or choose organic insect control methods if necessary. Never spray insecticides near hummingbird feeders.
  3. Keep cats indoors and take steps to discourage feral cats in your yard to protect hummingbirds and other backyard birds.
  4. Take steps to prevent bird-window collisions by placing hummingbird feeders appropriately in relation to windows and breaking up window reflections near where the birds feed.
  5. Clean hummingbird feeders regularly and use the proper hummingbird nectar recipe to provide appropriate nutrition for backyard hummingbirds.
  6. Avoid red dye in hummingbird nectar and nectar concentrates. It is not necessary to attract the birds, and could cause harm for birds that consume a great deal of nectar.
  7. Choose native flowers to attract hummingbirds when planning your bird-friendly landscaping and maintain plants well to encourage healthy, abundant blooms. If possible, plant an entire hummingbird garden to entice these birds.
  8. Create a safe space for nesting hummingbirds in your yard so new families can mature safely and securely. Leave spider webs intact for these birds to use as nesting material.
  9. Keep hummingbird feeders in sheltered areas away from wind and rain, and take steps to keep hummingbird nectar from freezing when poor weather threatens.
  10. Support local hummingbird organizations, including feeding stations, banding stations, and licensed rehabilitators. It takes extra training and skill to help hummingbirds, and supporting these facilities will lead to better hummingbird care and conservation.

By knowing how hummingbirds are threatened, it is easy to take steps to help with the conservation of these tiny, enchanting birds.
