The straight-sided drinker from Crown offers easy access for birds to drink without bending down. It has a wider bowl for more drinking space, ideal for larger birds. Fill the container by placing it upside-down.
The advantage of the straight-sided drinker is that the birds can drink without having to duck under the bulge of the water container. The bowl is also wider, allowing more drinking space. Certainly these are more suitable for larger birds. The container can be stood upside-down for filling.
