Included cases were pet psittacine birds that were prescribed haloperidol between 2012 and 2022 and had sufficient follow-up information available to assess efficacy and adverse effects.

Haloperidol was prescribed for 17 birds with feather destructive behavior, 1 bird for excessive sexual behavior, and 1 bird prophylactically after surgery of the uropygial gland. The most common species prescribed haloperidol were grey parrots (n = 5) (<i>Psittacus erithacus</i>), umbrella cockatoos (n = 4) (<i>Cacatua alba</i>), and <i>Pionus</i> spp. (n = 2).

Viscoelastic testing requires only 0.2 mL of blood and is useful in diagnosing and treating hemostatic disorders. Currently, there is no standardized coagulation testing method across bird species. In this cross-sectional study, a viscoelastic coagulation device, the Entegrion Viscoelastic Coagulation Monitor-Vet (VCM-Vet), was evaluated. Blood samples were obtained from 26 Hispaniolan Amazon parrots (HAPs) (<i>Amazona ventralis</i>) under manual restraint. Results were recorded on the device as graphical output with quantitative viscoelastic measurements. Results were reported using standard rotational thromboelastometry terminology, including clotting time, clot formation time, alpha angle, maximum clot firmness, clot firmness amplitude at 10 and 20 minutes after clot formation, and clot lysis at 30 and 45 minutes. The median clotting time was 463 seconds (reference interval: 56-1635 seconds), the mean clot formation time was 704.7 seconds (reference interval: 172-1697 seconds), the mean alpha angle was 27.3 (reference interval: 7-60), and the mean maximum clot firmness was 15.4 (reference interval: 7-25). Statistical analysis found that all parameters were normally distributed aside from clotting time in seconds. There was no appreciable breakdown of the clot during the 60-minute device runtime, and there was no significant difference in any parameter based on sex. The VCM-Vet produced clotting times for this population of HAPs and enabled the creation of reference intervals.

Sedation is often necessary for sample collection, imaging, or treatment. Dexmedetomidine has been previously used to sedate birds, often with other sedatives. Butorphanol tartrate, a Schedule IV controlled substance, is commonly used but presents regulatory challenges. Nalbuphine hydrochloride, an opioid with similar receptor affinity to butorphanol, has potential as a noncontrolled alternative. Although information regarding nalbuphine use in birds is limited, its noncontrolled status makes it more accessible. The purpose of this study was to determine the effective dose to produce sedation in 50% (ED<sub>50</sub>) of patients and to estimate the calculated effective dose of dexmedetomidine in combination with either butorphanol (DexBut) or nalbuphine (DexNal) in domestic hens to sedate 99% of patients (ED<sub>99</sub>). Eighteen 33-week-old laying Buff Orpington hens were divided into 2 groups: one receiving DexBut (n = 9) and the second receiving DexNal (n = 9). Each hen was sedated with varying doses of intramuscular dexmedetomidine with a constant dose of either 2 mg/kg IM butorphanol or 12.5 mg/kg IM nalbuphine by an up-and-down design.

The major objectives of this research were to investigate whether IBV infections exist among houbara bustards at the National Wildlife Research Center in Taif, Saudi Arabia, and to determine the prevalence of this virus in this bird population. Fifty-eight oropharyngeal and cloacal swabs were gathered from 29 unvaccinated birds without clinical signs between 2017 and 2023. Extraction of complete RNA from the swab samples and reverse transcription-polymerase chain reaction testing were used to identify IBV. The prevalence of IBV in this population was 37.9% (11 of 29; 95% confidence interval, 20.2-55.5%), indicating transmission asymptomatically among captive houbara bustards. This research identified for the first time that houbara bustards were exposed to IBV, and that this exposure is not uncommon.
