Nest FAQs
  • When will the female lay her eggs?
    Egg laying commences after nest building is completed, which is indicated by the martins lining the nest with soft, often times green, leaves.
  • How many eggs do purple martins usually lay?
    Females lay from two to seven all white eggs. The average clutch size is four to five eggs.
  • How long will it be before the eggs hatch?
    The female incubates the eggs for approximately 15 days, at which point the babies hatch.
  • When do the babies leave the nest?
    The babies are ready to fledge, at anywhere from 26 to 32 days old. They continue to depend on their parents for food, for a couple of weeks after leaving the nest.
  • How long has the UHCL colony been active?
    The first season with purple martins nesting at UHCL was 2008. They have been returning every year since then.
  • What is the greatest threat to the purple martins on campus?
    The greatest threats to the purple martin's survival on campus and in general are two non-native cavity nesting birds--the European starling and the English house sparrow. Both of these species are very aggressive, and for the past 60 years have displaced large numbers of purple martins by taking over the housing intended for the purple martins.
