“…Thus the feeding frequency of the red-footed falcon approximates to the feeding frequency of insectivorous songbirds, considering the brood number (Smith et al 1988). These big differences together with the role of the parents in the feeding of their young need to be studied more specifically and to be verified based on a larger data set.…”

Foraging opportunism and feeding frequency are less studied parameters of behaviour in insectivorous falcons, many of which are endangered bird species. In this short study, prey composition and feeding frequency of red-footed falcon (Falco vespertinus) nestlings were studied using the method of camera recordings during seven days in July 2017 in southwestern Slovakia. Camera recording analyses of 2–3 chicks (14–26 days old) in three nests revealed a significant preference for insects (97%, n = 305 prey items), of which the Italian locust (Calliptamus italicus) was highly predominant (54%). We also found very high average chick feeding frequency (9.9 feedings per hour, n = 29 hours 22 min of regular observations), whereby the females fed their young ones more frequently (64.9%, n = 305 feedings) than the males (35.1%). Analyses of food composition in adverse weather conditions showed that unfavourable weather had a negative effect on chick feeding frequency, and in rainy weather the males fed significantly less than the females.

“…Feeding nestlings demands large amounts of parent's time and energy, spent mainly when searching and capturing preys (Mock, 1991). One way to maximize the cost-benefit budget is to search for large prey, therefore reducing the number of foraging bouts and increasing time of nestling attendance (Fitzpatrick, 1981;Smith et al, 1988). We describe here the foraging behavior of, and food items used by, P. sulphuratus parents feeding nestlings in the Pantanal floodplain, southwestern Brazil.…”

Foraging of Great Kiskadees (Pitangus sulphuratus) and food items offered to nestlings in the Pantanal

Feeding of Pitangus sulphuratus (Tyrannidae) nestlings have been poorly studied. Here we describe the foraging behavior of a P. sulphuratus pair and the searching and offering time of food items to nestlings in the Pantanal, Brazil. Data collection was carried out over 25 days on the outskirts of the Base de Estudos do Pantanal building, inhabited by insectivorous bats. Records were based on direct observations with the help of binocular. The pair required little time for searching for small insects and fruits, but these items comprised a little amount of food per event of capture. Some large prey was more time-costly for searching, but the long period that these food items were offered to nestlings overcompensated the searching time. Considering the time of feeding nestlings (benefit) in relation to the searching time by the parents (cost), bats and snails are the most advantageous items for P. sulphuratus parents feeding nestlings at the study site.Keywords: feeding behavior, foraging strategy, nestling diet, parental care, predation. Forrageamento de bem-te-vis (Pitangus sulphuratus) e itens alimentares oferecidos para ninhêgos no Pantanal ResumoA alimentação de ninhêgos de Pitangus sulphuratus (Tyrannidae) tem sido pouco estudada. Descrevemos, neste estudo, o comportamento de forrageamento de um casal de P. sulphuratus e o tempo para busca e oferta de itens aos ninhêgos, no Pantanal, Brasil. A coleta de dados foi realizada durante 25 dias nas proximidades do prédio da Base de Estudos do Pantanal, habitada por morcegos insetívoros. Os registros foram baseados em observações diretas com auxílio de binóculo. O casal demandou pouco tempo de busca para a captura de pequenos insetos e frutos, porém esses itens representaram pouca quantidade de alimento por evento de captura. Algumas presas grandes demandaram mais tempo para busca, mas o longo período que esses itens foram oferecidos aos ninhêgos sobrecompensou o tempo de busca. Considerando-se o tempo de alimentação dos ninhêgos (benefício) em relação ao tempo de busca pelos pais (custo), morcegos e caramujos são itens mais vantajosos para os pais de P. sulphuratus alimentar ninhêgos no local de estudo.Palavras-chave: comportamento alimentar, cuidado parental, dieta de ninhêgos, estratégia de forrageamento, predação.
