Rheas are large flightless birds, related to both the Ostriches and Emus but not as well known. They are the smallest in size(between 5-6Ft) and are distinguished from ostriches by their three-toed feet. There wings consists of large plumes of feathers which they use as a very effective distraction while running from danger. One male will mate with a number of females and he alone incubates the eggs and raises the young. The eggs are large and yellow in size and remarkably are only 35 days incubation. Males can be aggressive especially during the breeding season and make a deep booming noise during these months. I have never experienced aggression from females. They are a very inquisitive breed and curiosity will always bring them over to say hello, especially if they spot something shiny. They don't require a license but they need suitable room to run which they love to do.
Emus are also large, flightless birds. They are slightly longer and taller than the Rhea, but their wings are very small with no feathers. Again, the male incubates the eggs and raises the young. The eggs are large and a deep green in colour, they are 45 days incubation and impossible to candle. The chicks are very cute with there striped pattern and have great personalities. They are very playful and unlike the rhea seem to have no fear of dogs or other animals and they also love water. Unfortunately as they mature, males are generally aggressive during the breeding season, due to this reason they require a wild animal licence in Northern Ireland but not in Southern Ireland.
