Fall begins yet they are still breeding

Fall season official starts few days ago and to my surprise I recently found out that one of my breeding shama pair has few chicks in their nest.  For the last two weeks, I think the breeding season is over and with busy schedule, I didn't watch the birds much except come out to feed and change water.  I noticed few empty egg shells on the aviary floor last week but just think they are from previous clutch and the bird just moving them around.  Few days ago, I start to hear the chick call and the parents bring food to the nest.  So excited!  The parents starts to show sign of molting yet still be a dedicate parents and feed their chicks constantly.  I love keeping White-rumped shama! :)

  1. A clutch of chicks was recorded as late as December (in captivity). Although we do not have the fall or winter season here, it is definitely out of their natural breeding cycle. Which leads me to believe that there is no specific pre-defined breeding season in captivity.

  2. Dance: I think day light hours (day length) is the main factor to induce breeding in white-rumped shama and might be majority of tropical bird. Temperature, availability of food, and rain fall plays minor role in inducing the bird into breeding but available of live food will keep the bird continues breeding until the day light hours shorten.
    I gathered a few data about day light hours, rain fall, and temperature between three different place that has been know shama successful breeding: Saigon, Hawaii, and California and the common/similar data is day length. http://lacvietchoelua.blogspot.com/2009/12/weather-where-white-rumped-shama-can.html

    Also, Linda Hogan posted on her blog a while ago that lengthening daylight can induce her canary into breeding http://lacvietchoelua.blogspot.com/2010/01/article-about-making-breeding-simple.html#links
