Speer or his staff to add their comments… I do not know if I am the right person to fully answer your question, since it is basically a medical issue and I hope the WPT representatives will also ask Dr. Would greatly appreciate your input.ĭear Roxanne, Thank you for the kind words. I thought Staph was bacterial, not fungal. Fred also has an ongoing zinc issue (last 18 years) and wears a collar most of the time I only take it off for a few min-hrs to let him preen. He is outdoors much of the time, playing in the various fruit trees and local natives. I fear he will become AB resistant also, I do not want his immunity compromised. We were told it is because he picks at it however, my thought is that he picks BECAUSE he has and infection/fungus - which then worsens the issue. It occurs mostly in his right wing pit, but his left side is occasionally affected - to a lesser degree. ago, then I noticed yesterday that it has started up again in his left wing pit. He was given antibiotics (3 times in 1.5 yrs) mixed in his water. Originally I was told it was a fungal infection, then a staph infection. My goffins cockatoo (20 yrs old) has been having an on/off ‘infection’ in his wing pit the last couple of years. Cravens, a person whose expertise I greatly respect from reading his articles in the Redwood Empire Cage Bird Club newsletter.
Tool making cockatoos adjust the lengths but not the widths of their tools to function. “The way they inserted and discarded manufactured pieces of specific lengths differently depending on condition suggests that the cockatoos could indeed adjust their tool making behavior in the predicted direction but with some limits in accuracy,” Dr. “In future studies, we will provide less restrictive materials to assess whether Goffin’s cockatoos are cognitively capable of adjusting tool width in this situation.” “The shearing technique the birds use to tear the cardboard limits the narrowness of the resulting strips,” the study authors said. However, only one bird was able to make a sufficiently-narrow tool to successfully reach the food reward when the opening was at its narrowest. On average, all six birds made significantly longer tools than were required to reach the reward in all test conditions, with the birds tending to make increasingly long tools as the study progressed - perhaps as a risk-avoidance strategy. In every case, if a first-attempt tool was too short, the second-attempt tool would be significantly longer. They found that the birds were capable of adjusting the length of their cardboard strip tools to account for variations in food distance, making shorter tools when the reward was closer than when it was set farther away. The researchers supplied six adult cockatoos with large cardboard sheets to tear into strips as tools for the testing apparatus: a food platform with a food reward set at varying distances (1.6-2.4 inches, or 4-16 cm) behind a small opening which also varied in width (0.4-0.8 inches, or 1-2 cm).

Auersperg and co-authors aimed to address two main questions: can Goffin’s cockatoos adjust the properties of their tools to save effort, and, if so, how accurately do they attend to the properties of their tools relative to their respective function during tool manufacture?Ī Goffin’s cockatoo uses a cardboard tool to obtain food. “Nevertheless, they combine and modify environmental objects during exploration and play, which can cause individual tool innovations in captive and potentially also in feral individuals.” “They are also neither nest builders nor food cachers, which are believed to be important preconditions for the development of avian tool use.” Alice Auersperg of the Medical University of Vienna and colleagues. “The Goffin’s cockatoo is neither a specialized tool user nor a habitual tool user on a population wide level such as New Caledonian crows,” explained study lead author Dr. Image credit: Goffin Lab, University of Veterinary Medicine Vienna.Ĭaptive Goffin’s cockatoos are capable of inventing and manipulating tools, even though they aren’t known to use tools habitually. A new study by Auersperg et al supports previous studies on Goffin’s cockatoos showing that they can not only select, but create different tools depending on the task at hand.
