Evaluation of Health & Behavior of Birds of the Order Psittaciformes in a Rehabilitation Facility in Costa Rica Andrea Aplasca College of Veterinary Medicine Cornell University | Class of 2017 Outline • Introduction & Background • Objectives & Hypotheses • Methods • Results • Conclusions Health PE Hematology Fecal Analysis Behavior Foraging Flight Social Introduction & Background • Order Psittaciformes – 3 Superfamilies: • Psittacoidea, Cacatuoidea, Strigopoidea • 350+ species • Threatened or Endangered: 95 Major Threats • Habitat Loss • Poaching and pet trade • 1990-1994 ~2 million parrots moved internationally Confiscated animals Rehabilitation Facilities • A lot of unknowns! • History • Location of origin • Prior movements • Disease exposure Stress, Transport, Dense Multi-species Groups ! Increased Risk of Disease Why study parrots? • Improve welfare and rehabilitation of individual birds • Ensure safety of wild populations upon release • Increase general knowledge about each species • Individual animal health = Marker for population health Objectives 1. Develop and implement disease surveillance program for birds in facility 2. Evaluate behavior to identify animals suitable for release into the wild Hypotheses 1. Parrots in a rehabilitation facility exhibit higher prevalence of hemoparasites than free ranging birds in the neotropics 2. Animals with higher parasite loads (type and quantity) exhibit more clinical signs associated with decreased body condition or other signs of disease Methods: Location • Kids Saving the Rainforest – Costa Rica, Pacific coast – 501 (c)(3) non-profit organization – ~ 7km from Manuel Antonio National Park Methods: Species • Enclosure 1 – 7 Red Lored Parrots – 5 Crimson Fronted Parakeets – 1 Yellow Naped Amazon (Vulnerable) – 1 Mealy Amazon (Near Threatened) Methods: Species • Enclosure 2 – 9 Orange Chinned Parakeets • 2 reside within closed cage – 1 White Crowned Parrot – 1 Brown Hooded Parrot – 1 Olive Throated Parakeet – 1 Orange Fronted Parakeet (currently in clinic) Methods: Species • Clinic Animals – 1 White Crowned Parrot – 1 Scarlet Macaw Methods: Health Evaluation • Physical Exam Methods: Health Evaluation • Venipuncture • Jugular vein, basilic vein • 25 or 27 gauge needle • 1 cc heparinized syringes • Heparinized blood tubes • Complete Blood Count • WBC Count – Estimated & Leukopet • Packed Cell Volume • Total Solids Methods: Health Evaluation • Fecal Analysis – Direct – Float (passive) • Sodium nitrate solution (SG ~ 1.25-1.27) – Float (centrifugation) *Gold Standard* • Sheather’s sugar solution (SG ~ 1.27) – Gram’s Stain Methods: Behavior 1.

Parrots in a rehabilitation facility exhibit higher prevalence of hemoparasites than free ranging birds in the neotropics 2. Animals with higher parasite loads (type and quantity) exhibit more clinical signs associated with decreased body condition or other signs of disease Hypotheses 1. Parrots in a rehabilitation facility exhibit d e t r o p p higher prevalence of hemoparasites than u S t o N free ranging birds in the neotropics 2. Animals with higher parasite loads (type and quantity) exhibit more clinical signs associated with decreased body condition or other signs of disease Hypotheses 1. Parrots in a rehabilitation facility exhibit d e t r o p p higher prevalence of hemoparasites than u S t o N free ranging birds in the neotropics 2. Animals with higher parasite loads (type e v i s u l c n o C and quantity) exhibit more clinical signs t o N associated with decreased body condition or other signs of disease Challenges: Health Evaluation • High stress physical exams • Sick bird may have “normal” blood values – What are the “normal” values?? • Fecal parasites – shed intermittently – Pooled samples? • Gram’s stain – very delicate process • No viral testing Challenges: Behavior • • • • • A LOT of animals! ~4.5 hrs per animal – Enough? Many observers – Inherent subjectivity Social structure affects behavior Less active during bad weather Additional Work • • • • • Examine effect of weather on behavior Is behavior different in AM vs. PM? Is behavior related to clinical findings? Definitive parasite IDs Soft release of identified birds Thank You! • Project Development – Dr. Maria Pia Martin – Dr. Noha Abou-Madi – Dr. Robert P. Moore – Mandy Kain • Project Support – Cornell University College of Veterinary Medicine Thank You! • Army of Volunteers for hours & hours of: – Observations, Observations, Observations – Keeping an eye on Hulk while wrangling parrots – Luring tiny parakeets into sunflower-filled cages Appendix Species Information • Red Lored Parrots (Amazona autumnaiis) – Pairs, groups, large flocks – Life span 80 yrs – Least concern • Crimson Fronted Parakeet (Psittacara finschi) – Single of mixed species groups – Least concern, forest edges, maybe increasing • Orange Chinned Parakeets – Large groups up to 50 birds – Small groups/pairs during breeding
