“…Micronesian starlings (Aplonis opaca) are the only other frugivorous vertebrates on the atoll, but they feed primarily on smaller fruit and fruit with smaller seeds (Baker, 1951;Jenkins, 1983). Coconut crabs (Birgus latro) feed on fallen fruit (Reyne, 1939;Holthuis, 1963) and may rival Pteropus as seed dispersal agents for some island tree species, but this aspect of crab biology is poorly understood (Wiles et al, 1991).…”

“…However, observers noted that the birds nested in both termitaria and soft-wooded trees before their extirpation from Guam ( Jenkins 1983, Marshall 1989). Although we were unable to evaluate difference between the thermal characteristics of nest cavities constructed in wood and those in termitaria, cavities made in wood by Acorn Woodpeckers, Melanerpes formicivorus, and Northern Flickers, Colaptes auratus, have also been shown to provide protections from solar heat gain and convective and radiative heat losses (Hooge et al 1999, Wiebe 2001).…”

We studied the relationship between microclimate and nest-site selection in the Pohnpei Micronesian Kingfisher (Todiramphus cinnamominus reichenbachii ) which excavates nest cavities from the mudlike nest structures of arboreal termites (Nasutitermes sp.) or termitaria. Mean daily high temperatures at termitaria were cooler and daily low temperatures were warmer than at random sites in the forest. Results also indicate that termitaria provided insulation from temperature extremes, and that temperatures inside termitaria were within the thermoneutral zone of Micronesian Kingfishers more often than those outside. No differences were identified in temperatures at sites where nest termitaria and nonnest termitaria occurred or among the insulation properties of used and unused termitaria. These results suggest that although termitaria provide insulation from thermal extremes and a metabolically less stressful microclimate, kingfishers did not select from among available termitaria based on their thermal properties. Our findings are relevant to conservation efforts for the critically endangered Guam Micronesian Kingfisher (T. c. cinnamominus) which is extinct in the wild and exists only as a captive population. Captive breeding facilities should provide aviaries with daily ambient temperatures ranging from 22.06 C to 28.05 C to reduce microclimate-associated metabolic stress and to replicate microclimates used by wild Micronesian Kingfishers.During nesting, birds employ a broad range of nest-site selection strategies to reduce environmental influences on survival and reproductive success

“…Micronesian Honeyeaters, along with most other native forest birds, were extirpated from Guam in the mid1980s with the arrival and range expansion of the brown treesnake (Boiga irregularis; Savidge 1987, Wiles et al 2003). Surveys on Rota, Tinian, and Saipan (the inhabited islands of the Commonwealth of the Northern Mariana Islands [CNMI]) have indicated that Micronesian Honeyeaters are less numerous on Saipan than on Rota or Tinian (Pratt et al 1979, Ralph and Sakai 1979, Jenkins and Aguon 1981, Jenkins 1983, Craig 1996 Engbring et al (1986) found that densities were greater on Saipan than on Tinian. On Saipan, Engbring et al (1986) counted 549 honeyeaters (mean of 2.25 birds per station Ϯ 0.14 SE), and estimated the total Micronesian Honeyeater population at 22,573.…”
