Filial imprinting is not restricted to non-human animals that are able to follow their parents, however. The filial imprinting of birds was a primary technique used to create the movie Winged Migration (Le Peuple Migrateur), which contains a great deal of footage of migratory birds in flight. The birds imprinted on handlers, who wore yellow ...
Partial imprinting occurs when alleles from both parents are differently expressed rather than complete expression and complete suppression of one parent's allele. [6] Forms of genomic imprinting have been demonstrated in fungi, plants and animals. [7] [8] In 2014, there were about 150 imprinted genes known in mice and about half that in humans ...
In animal behavior, the term "imprinting" refers to a special type of learning. Exact definitions of imprinting vary, but important aspects of the process include the following: (1) the learning occurs during a particular, critical period, usually early in the life of the animal; (2) the effects last a long time; and (3) the effects cannot be ...
Instead of burning a scar into the animal's skin, a freeze brand damages the pigment-producing hair cells, causing the animal's hair to grow back white within the branded area. This white-on-dark pattern is prized by cattle ranchers as its contrast allows some range work to be conducted with binoculars rather than individual visits to every animal.

Laboratory mice are often kept with several animals in one cage since mice are social animals, therefore it is necessary to have some method of identifying them individually. Earmarks may be used, [ 5 ] although non-traumatic methods such as tattooing their tails and painting spots on white mice with crystal violet or permanent markers can be ...
Lorenz studied instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of imprinting, the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching. Although ...
The history of ornithology largely reflects the trends in the history of biology, as well as many other scientific disciplines, including ecology, anatomy, physiology, paleontology, and more recently, molecular biology. Trends include the move from mere descriptions to the identification of patterns, thus towards elucidating the processes that ...
