All thoroughbred horses have the same birthday so as to standardise their ages for racing. In the Northern hemisphere all horses have their birthday on 1st January, but here it is 1st August.
This appears odd when a horse born at the end of July is already considered a yearling in August and then a 2 year old after its second August 1 even though it is really only one year and a few days.
Horses are very popular in children's literature, especially in novels for young readers. There are many horse-mad young girls visiting my library.
This collage shows some of the books that are popular. Except for Princess Evie's Ponies and the Bonny and Sam books these are not series. Aussie Nibbles and Aussie Bites both have several titles which feature horses.
In Australia, Alison Lester's books show her great love of horses and illustrator Patricia Mullins is often called upon when the title features horses because she too has a strong affinity with horses. Lightning Jack, her most recent title illustrated for author Glenda Millard is on the Picture Book of the Year shortlist. There are teacher's notes to accompany it here. Look for horse stories by American illustrator, Susan Jeffers as well because she too draws beautiful horses. See her picture book version of Black Beauty.
