Males transported since the projected 53,000 kcal to help you egg through the incubation, roughly the same as 5 kg off lipids (approximately 18–20% of their weight). Those people philosophy are probably a slight overestimate of your times required to possess incubation as the i assumed that incubation initiate at the time that as well as eggs try placed meanwhile as they are similarly included in a man (the latter assumption is really violated from inside the high handbags). Because the rhea males scarcely exit this new colony to feed, all of our imagine will bring a keen approximation of internet energetic price of incubation. This new estimated effective pricing for rheas is like you to definitely mentioned during the Emus (Dromaius novaehollandiae), a new ratite types where the men performs most of the incubation. Male Emus forgotten 7 kg (throughout the 17–20% of their fat) while in the 56 days of incubation ( Dawson mais aussi al. 1984). Also, Brown Kiwi (Apteryx australis) males forgotten ?23% of their body weight through the 91 times of incubation, even in the event for the reason that kinds incubation is actually partly distributed to females ( Taborsky and you may Brugger 1994).
