We located eleven roost/nest sites of the Forest Owlet, six of the Spotted Owlet, and five of the Jungle Owlet. It is thought that this owlet prefers subtropical and tropical dry deciduous forest, but has also been seen in moist deciduous forest or dense jungle. Diet of the Forest Owlet, Spotted Owlet, and Jungle Owlet in East Kalibhit Forests, Khandwa District, Madhya Pradesh, India (n = number of prey individuals). Prey abundance can also affect the dynamics of food-niche segregation. The diet of the Forest Owlet was dominated by small mammals (52.2%, by frequency), whereas invertebrates dominated the diets of the Spotted Owlet (58.1%) and Jungle Owlet (84.8%). H. blewitti es una especie depredadora generalista que se alimenta de varios tipos y tamaños de presa; A. brama se alimenta de mamíferos de tamaño grande y mediano, como también de invertebrados; y G. radiatum es una especie especialista que se alimenta principalmente de invertebrados y mamíferos de pequeño tamaño. data.) This was supported by a few other studies (Marti 1974, Jaksić 1983, 1985). 2004, Riegert et al. Prey availability varies with season and location, and comparative studies from different seasons and different habitats will improve our knowledge of the ecology of these little-known species. Bars with the same letter or no letters do not differ significantly. data). 2010, Zhao et al.

Overall the study area is composed largely of forest interspersed with agricultural lands and small residential areas (Fig. La dieta de las tres especies difirió significativamente. We studied owls in the protected forests of East Kalibhit Forest in Khandwa District of Madhya Pradesh in Central India. doi: https://doi.org/10.3356/JRR-17-00002.1. We measured the dietary overlap (DO) among species using Pianka's formula: We calculated the geometric mean weight of prey (GMWP; Compact Handbook of the Birds of India and Pakistan, Taxonomic studies of Indian Muridae and Hystericidae (Mammalia Rodentia). This could be due to a combination of factors: both the owls hunt mainly in cultivated fields (Santhanakrishnan et al. The dietary overlap was highest between the Forest Owlet and Spotted Owlet (56%), lower between the Spotted and Jungle Owlet (28%), and lowest between the Forest and Jungle Owlet (22%). (2005). The dietary overlap at class level was highest between the Forest and Spotted Owlets (56%), lower between the Spotted and Jungle Owlets (28%), and lowest between the Forest and Jungle Owlets (22%). The Forest Owlet consumed a wider array of prey (food-niche breadth [FNB] = 0.40) compared to the Spotted Owlet (FNB = 0.13) and the Jungle Owlet (FNB = 0.06). 2011, Patki et al. Food-niche breadth (FNB) was calculated using the standardized Levin's index (. (2002) observed foraging of one breeding pair and reported a high frequency of reptilian prey, followed by mammalian prey. (2005) reported that insects were more frequent than mammals in pellets of four pairs of Forest Owlets. They mainly feed on small prey animals that live in understorey vegetation within the owlet’s habitat, such as lizards and also amphibians, small birds, rodents and large invertebrates like grasshoppers. 2009). All three owl species consumed birds in small numbers. The GMWP of Forest Owlet was greater than that of the Jungle Owlet (t = 3.81, df = 338, P < 0.05). "As a tiger finds its place at the top of the food chain in the forests, the forest owlet, too, is at the top of the food chain and thus indicates a healthy forest. The diet of the Forest Owlet was dominated by small mammals (52.2%, by frequency), whereas invertebrates dominated the diets of the Spotted Owlet (58.1%) and Jungle Owlet (84.8%).
