    Abstract Aims: A novel
    Methods: Faeces were collected from South Island takahē in managed populations across two geographic locations within New Zealand, linked by extensive bird translocation. Faecal flotations were performed and oocysts collected were sporulated in sterile water at 25°C for 5 days. Morphometric measurements including length:width (L:W) ratios of oocysts and sporocysts were made of 65 oocysts using light microscopy under oil immersion. A retrospective histological review of archived post-mortem material from takahē was performed.
    Results: Oocysts were ovoid (mean L:W 1.2 (SD 0.1)) with mean dimensions of 18.0 (SD 0.8) × 15.2 (SD 0.7) μm, and walls 0.9 (SD 0.1) μm thick at the equator. A micropyle was absent and the oocyst residuum was present as a granular spherical mass. Four sporocysts were present and were elongate ovoid in shape (mean L:W ratio 1.5), with mean dimensions of 9.7 (SD 1.1) × 6.3 (SD 0.7) μm and each containing two sporozoites with anterior and posterior refractile bodies. This morphological description is distinct from other
    Conclusions: A novel
    Clinical relevance: Conservation of the endangered South Island takahē is reliant on human management of populations under varying degrees of captive management. An understanding of diseases affecting this host, including parasites and their identification as unique to the takahē or introduced from interactions with other hosts, is essential to the maintenance of overall bird health and informs management decisions in this recovery programme.

    Abstract Lead is a persistent, highly toxic heavy metal known to affect physiological function and survival in birds. Nestlings are particularly at risk as exposure during critical stages of development can result in life-long deficits. Urban environments are increasingly associated with high levels of contamination and lead exposure at the urban-wildlife interface can have significant population health effects on wildlife. Wellington has an established population of Kaka (Nestor meridionalis) and provides the ideal opportunity to study the risks of lead exposure in an urban context. We sampled 139 nestlings over two breeding seasons (2015/16 and 2016/17) and examined concentrations of lead in blood samples. Nestlings were subjected to a clinical and neurological examination. Lead concentrations of egg shells were measured to evaluate maternal transfer of lead to nestlings. Overall, 36.7 % of nestlings showed evidence of lead exposure based on blood lead concentrations, ranging from <3.3μg/dL to 42.9μg/dL, with no detectable clinical signs of toxicity. The pattern of exposure in the majority of nestlings is indicative of exposure from hatch via eggshells and also direct parental feeding of lead following hatch. Lead concentrations in this cohort of Kaka have the potential to contribute to morbidity and mortality in this species. The lack of measurable neurological or physiological deficits associated with lead exposure is suggestive of an innate tolerance to these concentrations of lead in this population. However, the well-described subclinical and persistent effects of lead suggests a need for continued monitoring of this toxicant and its effects on Kaka behaviour and neurodevelopment.

    Abstract A novel Eimeria sp. is described from the endangered South Island takahē (Porphyrio hochstetteri). Faeces were collected from South Island takahē in managed populations across two geographic locations within New Zealand, linked by extensive bird translocation. Faecal flotations were performed and oocysts collected were sporulated in sterile water at 25°C for 5 days. Morphometric measurements including length:width (L:W) ratios of oocysts and sporocysts were made of 65 oocysts using light microscopy under oil immersion. A retrospective histological review of archived post-mortem material from takahē was performed. Oocysts were ovoid (mean L:W 1.2 (SD 0.1)) with mean dimensions of 18.0 (SD 0.8) × 15.2 (SD 0.7) μm, and walls 0.9 (SD 0.1) μm thick at the equator. A micropyle was absent and the oocyst residuum was present as a granular spherical mass. Four sporocysts were present and were elongate ovoid in shape (mean L:W ratio 1.5), with mean dimensions of 9.7 (SD 1.1) × 6.3 (SD 0.7) μm and each containing two sporozoites with anterior and posterior refractile bodies. This morphological description is distinct from other Eimeria spp. described in hosts of the family Rallidae. The retrospective review of tissue was hindered by the poor quality of the preserved gut tissue, but coccidial organisms were able to be identified in the caudal ileum and caecum of a single bird. A novel Eimeria sp. was identified in the faeces of takahē. We propose this species be named Eimeria takahe. Conservation of the endangered South Island takahē is reliant on human management of populations under varying degrees of captive management. An understanding of diseases affecting this host, including parasites and their identification as unique to the takahē or introduced from interactions with other hosts, is essential to the maintenance of overall bird health and informs management decisions in this recovery programme.Abbreviations: L:W: Length:width

    Abstract To investigate the types of wildlife affected and outcomes of hospitalisation for native wild birds and reptiles admitted to three wildlife hospitals in New Zealand following predation by cats. We reviewed hospital records of three wildlife hospitals (Wildbase Hospital (WBH) in Palmerston North; The Wildlife Hospital – Dunedin (DWH); and The Nest Te Kōhanga (TNTK) in Wellington) for cases of native species with a submission history or diagnosis of predation by cats over the period 2006–2022. Frequency analysis and cross-tabulation of the data were carried out using the factors wildlife hospital, animal order, species, and case outcome. Native wildlife (n = 639) presented following predation by cats to the three wildlife hospitals comprised 598 (93.6%) birds from 31 species and 41 (6.4%) reptiles from eight species. The mortality rate of these patients combined was 61.8% (395/639), with the other 38.2% (244/639) being released from hospital to rehabilitation facilities, released to the wild, or, for a small number, put into permanent captive placements. The most common species of birds admitted due to predation by cats were tūī (Prosthemadera novaeseelandiae; n = 173), silvereyes (Zosterops lateralis; n = 142), sacred kingfishers (Todiramphus sanctus; n = 100) and kererū (Hemiphaga novaeseelandiae; n = 70). There was an overall trend to increasing numbers of wildlife admitted for predation by cats over the period of this review, but the different operating periods of the three hospitals should be considered. Each of the three hospitals saw a different mix of species, with Wellington's TNTK seeing the widest diversity of species affected. Predation by cats was a common cause of native birds and reptiles being admitted to all three wildlife hospitals and a diversity of urban and rural wildlife were affected. Predation by cats causes significant mortality in wildlife patients admitted to wildlife hospitals despite best current treatment. Cat management strategies in Aotearoa New Zealand should consider the welfare and health of wildlife.

    Abstract Case history: Two clusters of mortality among endangered tūturuatu/tchūriwat'/shore plover (
    Clinical findings: In 2016, four chicks were noted to become weak, have increased vocalisations and closed eyes prior to death. The remaining chicks were treated for 5 days with amoxycillin/clavulanate orally twice daily. Water containers and brooders were cleaned and disinfected with chlorhexidine. No further mortality was seen.In the 2022 cluster, three adult breeding birds died acutely and five others showed inappetence, weight loss and diarrhoea approximately 10 days after heavy rains flooded the local river. The five birds were treated with amoxycillin/clavulanate orally twice daily and oral fluids for 5 days. Two birds died and three survived. No breeding occurred in the aviaries in the following season.
    Pathological findings: In 2016, the chicks showed pulmonary changes ranging from congestion and oedema to heterophilic inflammation consistent with septicaemia.In 2022, the adult birds showed proliferation of bacteria in the distal small intestine associated with mucosal ulceration and heterophilic infiltration. Acid-fast staining of the caecal contents in one bird showed organisms consistent with
    Laboratory findings: Aerobic bacterial cultures of the lung and liver of two affected chicks carried out in 2016 showed heavy growth of
    Clinical relevance: Fluctuations in water quality associated with mammalian faecal bacteria can adversely affect bird health and impact on captive rearing of endangered wildlife.

    Abstract Aims: To investigate the prevalence of lead exposure in hens and eggs from backyard poultry in a sample of Auckland households, the relationship between concentrations of lead in the blood of the hens and in the shells and yolks of eggs from the same household, and to examine associations with measures of hen health, environment and husbandry factors.
    Methods: Thirty households participated in the study from August to November 2016, each providing one adult hen for sampling, an egg from the household if available, and completing a questionnaire on hen husbandry. Concentrations of lead in blood were determined using a portable lead analyser. Eggs were analysed for concentrations of lead in the yolk and shell using inductively coupled plasma mass spectrometry after biological digestion with a mixture of nitric and hydrochloric acid.
    Results: Twenty three of 30 hens (77%) showed evidence of lead exposure, with median concentrations of lead in blood of 0.77 (min <0.16, max 8.02) μmol/L. All eggs showed evidence of lead exposure, with concentrations of lead in the yolk ranging from 0.003-1.07 mg/kg, and concentrations of lead in the eggshell ranging from <0.1-0.82 mg/kg. A positive correlation existed between concentrations of lead in the blood of a hen and concentrations of lead in egg yolk from the same hen (R
    Conclusions and clinical relevance: There was a high prevalence of lead exposure in this sample of Auckland backyard chickens, with the majority of hens being sub-clinically affected. Associations were found between concentrations of lead in the blood of the hens, and properties with homes built before 1941 and clad in weatherboard. Concentrations of lead in over half the egg yolks sampled were at levels sufficient to warrant human health concern. The assessment of concentrations of lead in backyard poultry and eggs intended for human consumption is recommended to protect human and bird health.
