Humming Bird Window Alert (set of 4)

Dispite having exceptional site, birds have a difficult time seeing glass. Insted, they see the reflection of the sky and plants in the glass, which they think indicates a safe area to fly, particularily if they are startled or threatened. Large picture windows and / or corner windows can be extremely dangerous. Strong windows can kill a bird on impact, or it can stun them, unfortunatly leading to death later in the day or next, if they suffer internal injuries or bleeding. This can happen folks, to our indoor bird AND outdoor birds. Window alerts can prevent this.
