MORBIDITY (Significant illnesses/issues facing this species this year):

- Squamous cell carcinoma (SCC) of the casque in Buceros bicornis (giant Indian or greater hornbill) presented in a 9th case (captive female) which had been surgically debrided and recurred.  It is currently under treatment using the anti-angiogenesis treatment which had been nearly successful on a prior case of SCC.

 Reminder:  SCC has been detected earliest by casque and skull radiographs. 
These images are recommended as a baseline for all adult Buceros hornbills with repetition annually for giant hornbills.  If this condition is suspected, please contact Veterinary Advisor (K. Gamble) ASAP to discuss diagnostics, treatments, and after-care.

- Uropygial gland carcinoma (L. Howard) presented in a single group of carmine bee-eaters which required surgical extirpation of the uropygial gland with some even prophylactically excised.

- Casque issues of excessive flakiness and soft lesions in black and white casqued hornbill and trumpeter hornbill which has not to date been concluded as neoplastic.

- 1.1 Abyssinian ground hornbill with intermittent hematochezia and melena – under investigation.

MORTALITY (Causes of death in this year):

  1. 0.2 Rhino hornbill from cardiac failure with atherosclerosis which bears striking resemblance to another 0.1 rhino hornbill from a third collection with similar signs.  0.1 Wrinkled hornbill which may have also been cardiac.
  2. Of these four birds, two were recent collection transfers and the other two were in nesting.

Micronesian kingfisher (MKF) pathology survey (S. Terrell):  A variety of causes of mortality were recorded in 2006 with no clear trends.  Cases reported to the SSP pathologist included:
          Skeletal malformation resulting in euthanasia
          Aspiration pneumonia
          Bacterial yolk sac infection of a neonate
          Mycobacterium simiae infection*

          Colonic impaction in an adult*see active research project section

BIRTHS: 

See Chair reports.

ANESTHESTIC PROTCOLS

(Please list successful and unsuccessful protocols)Isoflurane by facemask then maintenance by endotracheal tube remains the protocol of choice.

VACCINE RECOMMENDATIONS

(Vaccine reactions, new vaccines to be considered)None currently recommended although institutions should consider West Nile virus per area.  Additionally, discussion has been held about avian influenza vaccination.  Current USDA approval has only been received for CITES I and II and Endangered Species Act-covered birds.  Although this applies to many of the Coraciiformes TAG and AI vaccinations to date in Europe have not adversely affected most species – in fact, largely limited to capture trauma for smaller avian species, several cautions must be made.

Vaccination for AI at this time will:

  1. require participation in surveillance impact transfer of birds between institutions – although discussions are on-going to minimize the impact to intra-AZA transfers
  2. prevent re-introduction of species in many situations – most specifically Guam has declared that serologically positive AI birds will not be returned to Guam.

CONTRACEPTION

(Methods used, successes, failures)None currently recommended aside from removal of eggs or separation of gender.

ACTIVE RESEARCH PROJECTS:

  • Internal Anatomy of the Hornbill Casque (K. Gamble) – Manuscript has been accepted and will be published in the Journal of Avian Medicine and Surgery in March 2007.
  • Uropygial Gland Secretion Pigmentation of the Casque of Asian Hornbills  (Gamble, Dierenfeld) - In 2006, uropygial gland samples from collected AZA institutions were submitted to Milan University (completed) and Arizona State University (completed) for analysis of carotenoid profiles.   Moving forward, results from these analyses will be correlated through an odds-risk analysis with history of squamous cell carcinoma affected birds, their mates, and three age-matched controls – one B. bicornis unaffected housed in a US collection, one B. rhinoceros housed in a US collection, and one B. bicornis housed in an EEP collection.In 2007-08, uropygial gland samples will be solicited from EEP holding facilities to match the ages and genders of those submitted from AZA collections.  Although active field participation occurred in the Asian hornbill population with ongoing projects, permits for uropygial gland secreta collection and export were not successfully received so in situ comparisons remain unavailable at this time.  Efforts to work through in situ country zoological facilities will be resurrected.

 Mycobacterium simiae infection in Micronesian kingfishers (Travis, Junge, Terrell) - manuscript in-press in the Journal of the American Veterinary Medicial Association describing recent cases of M. simiae in MKFs.  Publication expected in early-mid 2007.

  • Determination of Nitrogen Requirements of Aceros and Buceros hornbills (Foeken, de Vries, Hudson, Sheppard, Dierenfeld) – manuscript accepted by Zoo Biology and currently in revision.

NUTRITIONAL RECOMMENDATIONS:  

No new recommendations at this time. 

NEW HEALTH CARE RECOMMENDATIONS:

No changes from the published guidelines that were reviewed and posted in April 2006.  This material is reviewed annually.

SSP/TAG PROTOCOLS:

Pathology survey:  Minimal reports were received from 2005 and 2006.  Reminder:  Necropsy reports from any and all coraciiform mortalities are requested at the time of histologic diagnosis.

Historic (1990-2004) reports are still needed from:  Attleboro, Aurora, Birmingham, Bloomington, Boston (NEAQ), Brevard, Bridgeton, Brownsville, Cape May, Brookfield, Cleveland, Coal Valley, Columbia, Dallas World Aquarium, Denver, Des Moines, Dickerson Park, Duluth, Eureka, Franklin Park, Gainesville, Glen Oak, Granby, Green Bay, Greenville, Gulf Breeze, Hancock, Hattiesburg, Jackson, Jacksonville, John Ball, Kansas City, Lafayette, Langley, Los Angeles, Lowry, Lufkin, Mill Mountain, Nashville, Norfolk, NZP (CRC and Zoo), Oakland, Ocean Journey, Oklahoma City, Orlando, Palm Desert, Panama, Philadelphia, Phoenix, Pitts CA, Pittsburgh, Providence, Quebec, Redwood, Rockton, Safari West, San Antonio, San Diego Zoo, Sanford, Sea World (Florida, Texas, California), Sedgwick, Sioux Falls, St. Augustine, Staten Island, Syracuse, Tautphaus, Topeka, Tucson, Valley, Waco, Wahpeton, West Palm Beach, World Bird.

If your institution is on this list, please coordinate with your veterinarian to check mortality logs (1990-2004) and submit records as they are available to maintain the depth and utility of this database.  If you did not have any deaths during this time or do not display the Order, please let the Veterinary Advisor (K. Gamble) know so that you inventory is accounted.

INFORMATION FROM THE FIELD: 

See active research projects and Chair report.

NEW REFERENCES FOR THE BIBLIOGRAPHY/WEBSITE:

Coraciiformes TAG Bibliography (K. Gamble) – This project is maintained with new publications entered as they arrive and are identified.  When you publish about the Order, please send the citation to the Veterinary Advisor for entering into the database and reprints.  Books and chapters will be reviewed in the upcoming year for entry of literature citations if not present in the database. 

Annual update was submitted to the TAG webmaster for posting – it currently contains 858 citations.
