“…As expected, the measurements and shapes of the beaks showed variations among the species analysed since they are birds belonging to different families. The birds exhibit a wide variety of beak shapes and sizes, which are adapted to allow them to explore a tremendous diversity of food resources, besides using the beaks for cleaning/preening, feeding offspring and courtship (Darrow & Bennett, 2022;Tattersall et al, 2017). considering that these are openings of the nasal cavity (Evans, 2016).…”

“…The beak width was variable, with the maxillary rostrum being greater than the mandibular rostrum in the toco toucan and smaller in buff‐necked ibis, while in the red‐legged seriema, it was practically the same. The rhamphotheca grows continuously in birds, and any change in keratin production can cause beak deformation (Tattersall et al., 2017; Darrow & Bennett, 2022). However, the growth rate of beak keratin is species‐dependent; for example, the rhinotheca of toco toucan has annual growth of 0.25 cm (Olsen, 2003).…”

This study aimed to evaluate the beaks of three species of birds using radiography and computed tomography (CT). The mean lengths of maxillary and mandibular rostra on radiographs were highest for toco toucan, followed by buff‐necked ibis, and least for red‐legged seriema birds. The height and width of maxillary and mandibular rostra measured on CT had mean values highest for toco toucans, followed by red‐legged seriema, and least for buff‐necked ibis. Except for the proximal region of the maxillary rostrum, the HU values were positive for other regions of the maxillary and mandibular rostra in the buff‐necked ibis and red‐legged seriema and negative in all for the toco toucan.

“…Strategies for the management of bone damage and infections, which cause large segmental bone defects, have been constantly improved in human patients (1,2). Some treatment strategies have also been applied to veterinary patients, including birds, with reports of distracting osteogenic, bone transport, or use of the demineralized bone matrix (3)(4)(5). The choice of treatment in avian should be guided by factors such as the complexity of the surgical procedure and learning curve, bone involved, method of stabilization, cost, and prognosis for return to function, among others.…”

The utilization of antibiotic-loaded cement spacer in the induced membrane development has been a debate topic in human medicine. To the best of the author's knowledge, these combinations have not yet been evaluated in birds. Therefore, this study assessed induced membrane formation using radiography and histology, in a segmental defect of a chicken radius, with or without the addition of cefazolin. Thirty 18-month-old healthy chickens were divided into two equal groups: G1—bone defect filled with bone cement; G2—bone defect filled with cefazolin powder-loaded bone cement. Radiographic examinations of the left forearm were taken immediately after surgery and at 7, 15, and 21 postoperative days. For the collection of the induced membranes, five chickens in each group were euthanized at 7, 15, and 21 days after surgery. Radiographically, the bone cement was identified as a radiopaque structure occupying the bone defect in both groups. Mild new bone formation in at least one of the fractured extremities of the bone defect was seen only 21 days after surgery in most chickens. Histologically, there was no difference in the mean thickness of the induced membrane between groups at all time points. Multifocal multinucleated cells differed between groups at 7 (G1 > G2) and 21 (G2 > G1) days after surgery. Mononuclear inflammatory infiltrate differed between groups only on day 21 (G1 > G2). Fibrous tissue proliferation did not differ between groups at all evaluation times. Blood vessel density differed only at 21 days postoperatively (G2 < G1). Multifocal areas of cartilage differed between groups at all time points (G1 > G2). In conclusion, cefazolin mixed with bone cement did not affect thickness of the induced membrane, but did result in a negative effect on some histological aspects, such as fewer vessels, less multifocal areas of cartilage, and persistence of inflammation.
