Diamond Doves feed primarily on the ground in the wild, so the style of feeder you choose should accommodate their natural preference for eating at floor level or from low-mounted dishes. Open-top ceramic crocks or small stoneware bowls are ideal because they are heavy enough to resist tipping, easy to clean, and allow doves to see and access seed without navigating hooded or tube-style dispensers designed for hookbills.
Covered seed hoppers can work well for reducing waste and keeping seed clean, but choose a model with a wide, low-profile opening. Doves will not reach into narrow slots or push past flaps to access food the way parakeets or canaries will. The hopper opening should be at least two inches wide and positioned at the dove's standing height to encourage comfortable feeding posture.
Water dispensers for Diamond Doves should be open and shallow. Doves drink by immersing their bill and drawing water upward through suction, unlike most other cage birds that tip their heads back to swallow. Tube-style water bottles with ball-bearing spouts are not appropriate for doves, as they cannot operate the mechanism. A small, heavy ceramic dish or a clip-on open water cup is the best option.
Maintain at least two feeding stations and two water sources in any enclosure housing a pair or more of doves. This prevents dominant birds from monopolizing resources and ensures that all birds can eat and drink without competition. Clean all food and water containers daily with hot water, and perform a thorough scrub with a dilute vinegar solution at least once per week to prevent bacterial and algal buildup.
