The critically endangered Hawaiian Crow or ′Alalā (Corvus hawaiiensis) is currently extinct in the wild and the remaining 115 individuals are being captively managed on Hawai′i and Maui Islands by the Zoological Society of San Diego. Here we provide the first comprehensive analysis of the vocal repertoire of this species. We documented the vocal repertoire of three male-female pairs of ′Alalā during the 2012 breeding season at the Keauhou Bird Conservation Center (KBCC) on Hawai'i Island. Vocalizations were recorded using an automated acoustic recorder placed outside each of three aviaries housing each pair of ′Alalā. A total of 44 hours of recordings were analyzed to describe the structure of vocalizations, call characteristics, and vocal repertoire of this species. We identified 24 different call type categories with fundamental frequencies between 500 Hz-2 kHz. Variation within each call type was observed, as well as variation of similar call types among ′Alalā breeding pairs. Many calls contained a variety of nonlinear dynamical states, including deterministic chaos, frequency jumps, bifurcation, and varying harmonics and subharmonics. These findings provide important baseline information on ′Alalā vocal behavior that may assist future efforts to release these birds back into the wild.

This study compared immobilization of gemsbok (Oryx gazella) using thiafentanil-xylazine (TX) versus carfentanil-xylazine (CX). Twelve adult gemsboks were divided into two groups, TX and CX. Each group received either 6 mg thiafentanil (0.036 g/kg (0.032-0.040 μg/kg) and 20 mg xylazine (TX) or 3.6 mg carfentanil (0.021 μg/kg (0.017-0.024 μg/kg) and 20 mg xylazine (CX). Once handled, physiologic measurements were taken every 5 min for 20 min. There were few physiologic differences between the groups, although TX gemsboks were more hypertensive. Quality of induction, quality of recovery, depth of anesthesia, and muscle relaxation were subjectively assessed. Although TX gemsboks showed a trend for more-rapid induction and recovery postantagonist administration, this difference was not statistically significant. Similarly, there was a trend for TX animals to have smoother inductions and improved immobilization quality, but only the quality of induction was significantly different. These trends suggest that TX is preferable to CX when anesthetizing adult gemsboks. Copyright 2010 by American Association of Zoo Veterinarians.

A wild-caught Bowsprit tortoise (Chersina angulata) was received into quarantine and appeared clinically normal. Oral swabs for consensus herpesvirus polymerase chain reaction (PCR) and sequencing were obtained during routine quarantine, and a novel herpesvirus was identified. Comparative sequence analysis shows that this virus is a member of the subfamily Alphaherpesvirinae in the proposed genus Chelonivirus. Host/virus co-evolution appears to be common amongst herpesviruses and their hosts, and the most significant disease is typically seen when herpesviruses jump to related host species. Previous studies have found some diversity of herpesviruses in tortoises. This report expands the number of known herpesviruses of tortoises. It is reasonable to expect that there will be significantly different clinical consequences of different tortoise herpesviruses in different species, and that identification of host/virus relationships will aid in clinical management of tortoise collections. Further work is needed to determine the clinical implications of this and other tortoise herpesviruses in different tortoise species. © 2010 American Association of Zoo Veterinarians.

Although necrobacillosis remains a common condition of captive macropods, there have been limited reports of successful treatment modalities by which it can be treated. Comprehensive endodontic therapy with apicoectomy has been used reliably in human and domestic animal dentistry. This report describes a case of periapical osteomyelitis involving a mandibular incisor in a Parma wallaby (Macropus parma) that was successfully treated using these techniques in conjunction with low-level laser therapy at 810 nm, which was used for decontamination of the pulp cavity, anti-inflammatory, and biostimulatory effects.

This study investigates the chemistry of femoral gland secretions in the desert iguana,Dipsosaurus dorsalis (Lacertilia: Iguanidae), and discusses their possible functional significance. Electrophoretic and proton NMR studies indicated that the secretions are composed of approximately 80 % protein and 20% lipid material. Individual differences in polyacrylamide gel banding patterns of femoral gland proteins were found. Reflectance spectroscopy revealed that the secretions strongly absorb longwave ultraviolet light, a feature that may be important in the localization of secretion deposits in the environment.
