The aim of this study is to describe interactions between hummingbirds and ornithophilous species at Serra da Bodoquena in midwest Brazil, with focus on flowering phenology and pollination of these plant species. In two habitats, gallery forest and semi-deciduous forest, data on flowering phenology of ornithophilous species were collected monthly over 14 months. In addition, data on morphology and floral biology, as well as visitor frequency and hummingbird behavior, were recorded. The studied community contained eight ornithophilous plant species and six hummingbird species. The ornithophilous species flowered throughout the year, and the greatest abundance of flowers was at the end of the rainy season and the beginning of the dry one. The herit huingbird Phaethornis pretrei and feales of Thalurania furcata, were the most similar in floral resource use. Acanthaceae is the most representative family of ornithophilous plant species in Serra da Bodoquena and, thus, represents the main food source for hummingbirds. Ruellia angustiflora is especially important because it flowers continuously throughout the year and is a significant food resource for P. pretrei, which is the main visitor for this plant guild.
本研究旨在描述巴西中西部博多昆纳山脉蜂鸟与喜鸟植物物种之间的相互作用，重点关注这些植物物种的开花物候和授粉情况。在两个栖息地，即长廊林和半落叶林中，对喜鸟植物物种的开花物候数据进行了为期14个月的每月收集。此外，还记录了形态学和花生物学数据，以及访客频率和蜂鸟行为。所研究的群落包含8种喜鸟植物物种和6种蜂鸟物种。喜鸟植物物种全年开花，花朵数量最多的时候是雨季末期和旱季初期。蜂鸟Phaethornis pretrei和Thalurania furcata的雌鸟在花卉资源利用方面最为相似。爵床科是博多昆纳山脉喜鸟植物物种中最具代表性的科，因此是蜂鸟的主要食物来源。狭花芦莉草尤其重要，因为它全年持续开花，是P. pretrei的重要食物资源（P. pretrei是该植物群落的主要访客）。
