CoziBird Window Bird Feeder with Ultra Strong Suction Cup - Large Clear Acrylic Weatherproof Birdhouse (Heavy Duty Suction Grip)

The CoziBird Window Feeder uses a push/twist/lock system with Super-Force suction keeping it firmly attached year-round. No slipping, no falling - just reliable, close-up birdwatching.

Unlike designs that place four suction cups directly in the viewing area, this over-mounted suction system ensures an unobstructed view of the birds. The generous 10×10-inch size attracts a wide range of birds, including larger species like cardinals and blue jays.

Built for all-season grip, the deep-groove suction cup delivers up to 10× the holding power of standard cups. Tested to perform from -20°F to 120°F - in rain, snow, or sun. To install, press firmly on a clean window and turn the knob clockwise until tight.

Made from virtually indestructible, anti-yellowing polycarbonate for superior strength compared to standard acrylic designs. Removable self-draining feeding tray makes it quick and easy to refill with mealworms, vegetables, nuts, seeds, and fruit. Drain holes in the tray prevent moisture buildup, keeping the food fresh for your feathered friends.

Suction System Explained: By mounting the twist-lock suction unit over the feeder (above), rather than behind it, the weight of the feeder applies a downward force that pushes into the suction cup, enhancing its grip. This downward force reinforces the seal instead of pulling away from it - unlike rear-mounted designs, where the load creates a prying force that gradually weakens suction over time.
