Eucalyptus Wandoo

Globally, many forests and woodlands are in decline. The marked loss of canopy foliage typical of these declines results in reduced foraging resources (e.g. nectar, pollen, and insects) and, subsequently, can reduce habitat quality for woodland birds. In south-west Western Australia, patches of Eucalyptus wandoo woodlands have shown a decline in condition since at least 2002. We investigated how changes in E. wandoo condition affect the woodland bird community. Foraging activities of three bird species were recorded for 20 sites in Dryandra State Forest and Wandoo Conservation Park either by conducting watches on focal trees (‘sitting’ method), or following individuals through the woodland (‘following’ method). Condition assessments of trees used by the birds were compared with those for trees available at the study site. Weebills (Smicrornis brevirostris; canopy insectivore) displayed preference for healthy trees (low amounts of canopy dieback), whereas rufous treecreepers (Climacteris rufa; bark-foraging insectivore) preferred trees with a higher proportion of dead branches. Yellow-plumed honeyeaters (Lichenostomus ornatus; insectivore/nectarivore) foraged in older, larger E. wandoo trees having full canopies with few signs of tree decline. Tree declines, such as that happening in E. wandoo, alter the foraging resources and habitat available to woodland birds.

Eucalyptus Wandoo

IN 1908, Ron's grandfather, Issac Gray, took up an uncleared block of land 15 km north of Frankland in the south-west of Western Australia (see Fig. 1, Hobbs 2003). During that time he ran a few cattle in the bush and clearing of the native woodlands of Wandoo (white gum) Eucalyptus wandoo, J arrah E. marginata and Marri (Redgum) E. calophylla was slow and tedious. Ron's parents took over the farm in 1947, and with the advent of the bulldozer, clearing of Watkin's property and surrounding district began in earnest during the 1950s. Clearing continued as fast "as money permitted", until almost the last natural vegetation was knocked down in 1978 (Fig. 1). Annual pastures with some cropping (for supplementary feed) were the main source of fodder for sheep and cattle.

The Status

Mail surveys were sent to field staff of the Agriculture Protection Board of Western Australia to assess the distribution and status of four species of parrot in the agricultural region of south-west Western Australia in 1970, 1980 and 1990. The surveys indicated that the populations of the Regent Parrot (Polytelis anthopeplus) and the Western Rosella (Platycercus icterotis) have declined in range considerably since 1970. The populations of the Red-capped Parrot (Purpureicephalus spurius) and the Port Lincoln Ringneck (Barnardius zonarius) have suffered little or not at all during the same period. Factors which appear to have contributed to the observed changes in distribution and status include clearing for agriculture, dietary preferences, physiology, habitat requirements, altered fire regimes, grazing by exotic herbivores and reduced winter rainfall. These surveys have shown that species which were formerly considered common and widespread have declined with little comment having been made of these changes. The implications of this are serious, both for these formerly common species and for rarer bird species which have similar ecological requirements. The technique of mail surveys has considerable merit for quickly assessing the status of some species of birds, but will be limited by the expertise of the respondents and the degree to which the species in question can be observed.

Time Periods

This paper documents the bird community in a small (~15 ha) patch of remnant woodland New South Wales sheep? wheat belt (i) before Noisy Miners Manorina melanocephala were abundant in the patch (1972-79), (ii) after a dense miner colony became established (1980-1990), (iii) after the miners were removed (1991?92) and, subsequently, (iv) while extensive, dense plantings of native trees became established (1992-2006). Bird species richness in the patch was, respectively, 64, 18, 45 and 83 species in each time period. Totals for small (<120 g) bush birds, mostly insectivorous passerines, were 26, 0, 22 and 46 species in the respective time periods. Although this was an unofficial, unreplicated and uncontrolled activity, the results support those of previous similar studies that indicate that Noisy Miners are a major contributor to the local decline of many woodland birds. The results also affirm the value of a shrub layer to small birds.

The precise type-locality of the infrequently encountered Western Australian species Nascio chydaea Olliff, 1886 is redefined from 28˚44ʹS, 116˚24ʹE to 34˚11ʹS, 118˚19ʹE, and thus George Masters is identified as the original collector and January–February 1869 as the date of collection of its lectotype and paralectotype. The first larval and adult hostplant records, Eucalyptus wandoo and an unidentified Asteraceae species respectively, as well as three further distributional records from south-west Western Australia, are provided for N. chydaea and discussed. A colour photograph of its dorsal habitus is also provided, as well as a distribution map for this species. Relationships, general zoogeography and biology of all Nascio species are briefly discussed.

Habitat Variables

Censuses were taken in the springs of 3 consecutive years of the birds in twelve 2-ha sites in remnants of wandoo woodland in SW Western Australia. The sites were distributed between 3 vegetation types: (a) Eucalyptus wandoo open forest; (b) E. accedens open forest with Dryandra sessilis; and (c) Casuarina/Acacia low open forest. The 3 vegetation types had similar numbers of birds but different species diversities. Although the relative numbers in each group of species changed from year to year, the relative numbers were the same each year in the different vegetation types. The avian communities of (a) and (c) had a higher diversity than in (b). In (c) there were significantly fewer nectar and bark feeders than in (a) or (b), but more ground insectivores. In (a) there were significantly more parrots and leaf gleaners than in the other vegetation types, whereas (b) had very high numbers of nectar feeders but low numbers of ground/low shrub insectivores. Statistically significant relationships were established between the abundance of 13 of the most common bird species and habitat variables. These regressions showed that both floristics and structure strongly affected the abundance of a species. Between 42 and 95% of the variance in numbers was accounted for.

The decline of woodland birds that follows from habitat fragmentation, degradation and loss of connectivity is well reported in the literature. However, reports of immediate responses by birds to these events are scant. This study, in the eastern whealtbelt of Western Australia, detected that when half of a 10 ha remnant of Allocasuarina shrubland was chained (vegetation knocked over and largely killed), birds responded quickly; increaser species apparently benefited and decliner species became restricted to the remaining unchained remnant of shrubland. There was some correspondence between the trends in variety and/or abundance of arthropods with those of bird species richness. Two Near-threatened species, the White-browed Babbler Pomatostomus supercilious and the Crested Bellbird Oreoica gutturalis, were only detected in the non-chained part of the remnant. These findings clearly highlight the immediate ecological consequences of clearing of native vegetation, and highlight the importance of conserving even the smallest remaining fragments.

North Western

We document the flora that provides nectar for birds in monsoonal north-western Australia, and examine the relationship between floral morphology and bird morphology in the region. Twenty-four regular nectarivores (21 honeyeaters, two lorikeets, one white-eye) and 29 opportunist species have been observed probing the flowers of 116 species of plants from 28 families. Amongst the nectar sources, the Myrtaceae is dominant in both the number of species and frequency of use, followed distantly by the Proteaceae and Loranthaceae. Variation between bird species in patterns of use of different floral structures primarily reflected the habitats occupied rather than shared or co-evolved morphology. Woodland birds made particular use of staminiferous cups, mangal specialists particular use of open sepaliferous and petaliferous flowers, and forest specialists and habitat generalists intermediate use of these flower types. Bird–flower relationships in monsoonal Australia may be generalised because of a combination of the dominance of mass-flowering myrtaceous trees, aridity during past glacials that may have eliminated specialists from the system, and perhaps also because many nectar sources are shared with bats.

Significant Difference

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

Behavioral Traits

The urbanization of landscapes filters bird communities to favor particular species traits, driven in part by the changes that homeowners make to the amount and quality of habitat in yards. We suggest that an ultimate driver of these proximate mechanisms underlying bird community change with respect to urbanization is the likeability of species traits by urban residents. We hypothesize that bird species likeability, modulated by species traits, influences the degree to which homeowners alter the availability and quality of habitat on their properties and thereby affects species population sizes in urbanized landscapes. We refer to this new hypothesis as the Likeable, therefore Abundant Hypothesis. The Likeable, therefore Abundant Hypothesis predicts that (1) bird species likeability varies with species morphological and behavioral traits, (2) homeowners use trait-based likeability as a motivator to modify habitat availability and quality on their properties, and (3) residential habitat availability and quality influences species populations at landscape scales. We tested the first prediction of the Likeable, therefore Abundant Hypothesis using a survey of 298 undergraduate students at the University of North Carolina at Charlotte who were asked to rank their preferences for 85 forest generalist and edge/open country songbird species grouped according to 10 morphological and behavioral traits. Survey respondents preferred very small, primarily blue or black species that are insectivorous, aerial or bark foragers, residents, and culturally unimportant. On the other hand, respondents disliked large or very large, primarily yellow or orange species that forage on the ground and/or forage by flycatching, are migratory, and are culturally important. If the Likeable, therefore Abundant Hypothesis is true, natural resource managers and planners could capitalize on the high likeability of species that are nevertheless negatively affected by urbanization to convince homeowners and residents to actively manage their properties for species conservation.
