Question: What is the date of birth of the 'Woman with a Parrot' creator?

Knowledge 1: Woman with a Parrot
La Femme au perroquet ("Woman with a Parrot") is an oil painting on canvas by French artist Gustave Courbet. It was the first nude by the artist to be accepted by the Paris Salon in 1866 after a previous entry in 1864 was rejected as indecent. It is in the collection of the Metropolitan Museum of Art in New York city. [SEP] Knowledge 2: Gustave Courbet
Jean Désiré Gustave Courbet (; 10 June 1819 – 31 December 1877) was a French painter who led the Realism movement in 19th-century French painting. Committed to painting only what he could see, he rejected academic convention and the Romanticism of the previous generation of visual artists. His independence set an example that was important to later artists, such as the Impressionists and the Cubists. Courbet occupies an important place in 19th-century French painting as an innovator and as an artist willing to make bold social statements through his work.
Knowledge 1: Grey parrot
Grey parrots are also highly intelligent, having been shown to perform at the cognitive level of a 4 -- to 6 - year - old child in some tasks. New experiments have shown that grey parrots can learn number sequences and can associate human voices with those humans' faces. Most notably, Dr Irene Pepperberg's work with Alex the parrot showed his ability to learn over 100 words, differentiating between objects, colours, materials, and shapes.

Irene Maxine Pepperberg (born April 1, 1949 in Brooklyn, New York) is a scientist noted for her studies in animal cognition, particularly in relation to parrots. She is an adjunct professor of psychology at Brandeis University and a lecturer at Harvard University. Pepperberg also serves on the Advisory Council of METI (Messaging Extraterrestrial Intelligence). She is well known for her comparative studies into the cognitive fundamentals of language and communication, and was one of the first to work on language learning in animals other than human species (exemplified by the Washoe project), by extension to a bird species. Pepperberg is also active in wildlife conservation, especially in relation to parrots.
