After the young are on their own, the martins begin to leave the colony area to start assembling as larger flocks. These flocks may number in the hundreds. It is from these large gatherings that the martins will begin their long migration that will take them to South America. As the martins begin their long journey they leave their roosts in smaller groups, with the earliest arrivals usually being the ones that start their migration first. This exit may be spread out over several weeks with most of the martins in our area leaving by midSeptember.
Brazil is the largest country in South America and is host to a very large percentage of migratory martins. Martins do not nest or breed in South America. They are only residing there during our North American winter to secure ample amounts of insects for their diet and also undergo a process called molting.
This involves the shedding of the old feathers and replacing them with new feathers. All martins molt once a year. It is this process that male martins must go through to attain the almost solid steel-blue appearance of an adult martin.
