Hummingbird feeders come in a variety of materials, but two of the most popular options are glass and plastic. Both have their advantages and disadvantages when it comes to factors like durability, ease of cleaning, insulation, eco-friendliness, and more. Here we’ll look at the key differences between glass and plastic hummingbird feeders to help you decide which is best for your needs.
Durability
When it comes to durability, glass hummingbird feeders are generally sturdier and longer-lasting than plastic feeders. Glass is resistant to cracking, chipping, and breaking under normal use. Plastic can become brittle and degrade over time when exposed to sunlight and extreme temperatures. However, plastic feeders are unlikely to shatter if dropped, while glass ones can. So plastic may be preferable if you live in an area prone to earthquakes or have rambunctious pets.
The thickness of the glass used can also affect durability. Opt for feeders made from laboratory-grade borosilicate glass for maximum sturdiness. This type of glass is thermal shock resistant. Avoid very thin mass-produced glass feeders which are more fragile.
High quality plastic feeders made with UV-stabilized polycarbonate or acrylic can be quite durable as well. But inexpensive plastic feeders may warp, cloud, and degrade quicker. Overall glass edges out plastic in terms of average lifespan.
Ease of cleaning
Glass hummingbird feeders are typically easier to clean than plastic feeders. Glass has a nonporous surface that resists staining, buildup of mineral deposits, and sticking of sap or drips of nectar. It washes up nicely with mild soap and water. Plastic can absorb stains over time and harbor bacteria in tiny crevices if not scrubbed meticulously.
The smooth interior of glass also makes it less likely for insects and debris to get lodged in hidden areas. With plastic feeders, mold and mildew may develop if moisture gets trapped. However, some high end plastics like acrylic and polycarbonate can be fairly easy to clean as well.
Insulation
During hot summer months, the nectar in hummingbird feeders can easily spoil due to high temperatures. Plastic provides better insulation against heat than glass, keeping nectar cooler for longer periods of time. The thicker the plastic, the better it insulates. Thin glass does little to prevent the nectar from heating up.
This means you’ll likely have to change the nectar more frequently if using a glass feeder in hot conditions to prevent fermentation and mold growth. Adding ice cubes to the nectar can help, but this causes rapid dilution as they melt. Plastic feeders allow you to go longer between nectar changes. Insulated glass and double-walled plastic feeders provide better temperature regulation.
Visibility
One advantage of glass hummingbird feeders is that the clear material offers exceptional visibility. You can easily monitor the nectar level and spot any debris or buildup inside. Plastic tends to be cloudier, obstructing the view of the contents. So you’ll need to open and peer inside plastic feeders to inspect them.
The transparent nature of glass allows you to observe hummingbird behavior up close as they feed. Kids are especially delighted to watch the birds and ants moving inside glass feeders. Plastic feeders offer less of a show. However, some plastic feeders have brightly colored nectar with etched outlines so you can view the level.
Eco-friendliness
For environmental impact, glass feeders are likely the greener choice over plastic. Glass is an inert material that doesn’t leach chemicals into the nectar. It’s also fully recyclable. Plastics often contain bisphenol-A (BPA), phthalates, and other toxins that can contaminate the nectar to a small degree. These chemicals can also leach into the environment after disposal.
However, some plastic feeders are now made from plant-based materials like polylactic acid (PLA) which is more eco-friendly. Others use BPA-free, food-safe plastics. But standard plastic feeders pose more risks to health and the environment than glass. If choosing plastic, look for BPA-free versions.
Weather resistance
Plastic feeders tend to hold up better than glass in cold winter temperatures. In below freezing conditions, glass can become brittle and prone to cracking. Plastics remain flexible and resistant to fracturing. Extreme heat can cause plastics to warp and melt however.
During storms, glass is more susceptible to breaking if hit by flying debris. But plastic may crack if struck forcefully. Overall, plastic feeders tend to fare better than glass in harsh weather extremes.
Safety
When it comes to safety, plastic feeders may be the wiser option. As mentioned, glass can shatter into dangerous shards if dropped or knocked over accidentally. This can lead to injuries for kids and pets playing nearby. Plastic feeders simply break into larger pieces rather than sharp fragments if they fall and crack.
Young children should be supervised closely when around any style feeder. But plastic poses less risk for lacerations if an excited child knocks it off its hanger. For households with rambunctious pets who might leap and play around the feeder, plastic is likely the safest bet.
Cost
Glass hummingbird feeders tend to be more expensive than comparable plastic versions. The manufacturing process for laboratory-grade borosilicate glass is more complex than plastic molding, resulting in a higher price. Inexpensive mass-produced glass feeders are lower quality and have more flaws.
For a durable high capacity glass feeder, expect to pay $25 to $75. Well-made plastic feeders range from $10 to $30 typically. Cheap plastic feeders under $10 may not last long. So glass costs more upfront, but can save money in the long run versus replacing cheap plastic feeders yearly.
Style options
You’ll find a far wider range of styles and designs among plastic hummingbird feeders. Plastic lends itself to more elaborate shapes, colors, and detailing. Glass feeder styles tend to be more limited, often just clear spheres or cylinders.
But glass artisans can craft beautiful hand-blown glass feeders in an array of colors, shapes, and artistic styles. These are premium feeders costing over $100, giving you unique options beyond basic mass-produced styles.

Conclusion
When choosing between glass or plastic hummingbird feeders, there are good reasons to consider both options. Glass feeders excel in durability, visibility, ease of cleaning, and eco-friendliness. But plastic feeders are more affordable, offer better insulation, and come in more stylistic versions. They also pose less risk of injury if damaged.
For frequent use in a hot climate, a plastic feeder may be ideal to keep nectar fresher longer between changes. Those in cooler climates who want a durable, easy-viewing feeder may prefer glass. Eco-conscious consumers often select glass for sustainability. Households with rambunctious kids or pets may opt for plastic as a safety precaution. Individual style preferences will also play a role in the decision.
In the end, both materials can make excellent choices depending on your specific needs as a hummingbird feeder owner. Focus on finding a well-constructed feeder of either type that will provide years of service and birdwatching enjoyment.
