These hens often pass this trait on to their daughters. While there are no known subspecies of Pacific Parrotlets, many breeders believe these birds could be an unrecognized subspecies. Pacific Parrotlets are certainly the most fearless as well as curious of the Forpus species. They are also ...
Method for detecting and identifying the presence of biological substances derived from birds, and oligonucleotides therefor The invention concerns a method for detecting the presence of biological substances derived from birds, in particular from anseriformes, galliformes or struthiformes in a sample or...
The majority of the producers that did not know the rearing conditions of their birds had furnished cage systems (Table 2A). Possible explanations are that furnished cage producers are not as familiar with the different housing systems rearing farmers can utilize during rearing, there may be lack...
We first calibrated single‐isotope models that predict spatial isotope variability in raptor feathers (called isoscapes) by analyzing and compiling isotope data for juvenile birds with known origins in North America and comparing their values to existing isotopic baselines in precipitation (for δ2H) ...
