“…Little is known about their foraging ranges (Nyhagen et al, 2001), but for the common and widespread, generalist flower-visiting endemic gecko Phelsuma ornata in Mauritius, 89% of marked individuals were re-sighted on the next day less than 15 m from the place of release, while maximum dispersal range was < 90 m (Nyhagen et al, 2001). The foraging range of nectarivorous birds depends both on body size and behaviour (Craig et al, 1981;Gill and Wolf, 1975). For hummingbirds, these interconnected attributes can translate into different community roles (Feinsinger, 1978).…”

“…Fuchsia excorticata, a gynodioecious tree, is visited by birds (Thomson 1880; Craig et al 1981) and shares all of the above traits common in birdpollinated plants with the exception of strict red coloration. Instead, it exhibits a floral colour change, going from green with purple streaks to a uniform red (Kirk 1892).…”

Fuchsia excorticata is a gynodioecious tree (endemic to New Zealand) which is pollinated by honeyeater birds. Red, tubular flowers are common among bird-pollinated plants, and the tubular flowers of F. excorticata change colour from green to red. The purpose of the present study was to describe the timing of the colour change, dropping of the floral tube, and nectar production of F. excorticata and to determine how bellbirds iAnthornis melanura) and two introduced species of nectar robbers (Zosterops lateralis and Bombus sp.) respond to the different colour phases.Floral tubes fell off about II days after anthesis in both sexes, with colour change occurring on about Day-4 for female trees and on about Day-S for hermaphrodite trees. Green-phase hermaphrodite flowers produced significantly more nectar/day than did green-phase female flowers, while red-phase flowers did not produce nectar in either sex. All three floral visitors studied preferentially visited green-phase flowers and virtually ignored the nectarless flowers in the red phase. These results contrast with the general association between red, bird-pollinated flowers and the presence of a nectar reward. We suggest that the non-migratory habit of the New Zealand honeyeaters and the lack of native insect visitors to this species may account for this anomalous green-to-red colour change.

“…Hihi are omnivorous and forage for invertebrates, nectar, and fruits, which provide important nutrients in their natural diet (Craig et al, 1981;Rasch, 1985;Castro and Robertson, 1997); seasonal variations in foraging behavior reflect food availability throughout the year (Angehr, 1984;Castro, 1995;Perrott, 1997). Hihi nestlings are almost exclusively fed invertebrates provided by the parent birds for the first 8-10 days of life .…”

ABSTRACT:Nestling mortality in the endangered and endemic Hihi, also called Stitchbird (Notiomystis cincta), was studied over the 2008-09 breeding season at Zealandia-Karori Sanctuary, Wellington, New Zealand. Histopathology showed traumatic ventriculitis in seven of 25 (28%) dead nestlings. Single or multiple granulomas centered on chitinous insect remnants were found lodged within the gizzard mucosa, muscle layers, and ventricular or intestinal serosa. The insect remnants were confirmed as bee or wasp stings (Hymenoptera) using light and electron microscopy. Bacteria or yeasts were also found in some granulomas, and death was due to bacterial septicemia in four cases. Endemic New Zealand birds are likely to lack evolutionary adaptations required to safely consume introduced honey bees (Apis mellifera) and vespulid wasps (Vespula germanica [German wasp], and Vespula vulgaris [common wasp]). However, these insects are attracted to feeding stations used to support translocated Hihi populations. As contact between bees, wasps, and the endemic fauna of New Zealand seems inevitable, it may be necessary to minimize the numbers of these introduced insects in areas set aside for ecologic restoration.
