Szukana fraza: [Opis = "The maternal behavior of a short\-tailed shrew \(Blarina brevicauda\) in simulated natural conditions was described. The female shrew was seen to constrict the nest openings during lactation as well as reinforce the nesting material. Her activity, measured as time out of the nest, increased during pregnancy and increased greatly during lactation. The shrew retrieved her pups both by dragging and with a behavior similar to caravanning. Maternal behavior ceased completely on day 22, the time of weaning."]
