Time to Head South: Gulf Coast Bird Observatory

With temperatures still soaring in our area, it’s hard to think about fall but birds know it’s time for their fall migration. So, exactly how do they know? There are a number of factors. One way is the angle of the sun. Days are growing shorter and we have fewer hours of daylight. Summer crops are becoming scarce and less food is available. In the fall, baby birds are now mature enough to be on their own so Mom no longer has to tend to the youngsters. The location of the birds is important as well. Arctic birds may begin migrating as early as July while those closer to the equator start migrating in late September.

Although rare in the Greater Houston area, it is not unheard of to see a Broad-winged hawk (Buteo platypterus) in the Houston area. These raptors have chunky bodies and a small reddish-brown head. Their tales are black and white striped similar to a raccoon’s tail. The undersides of the wings are bordered in dark brown. These hawks live in forests and spend the majority of their time under the canopy of the trees. Here they look for small animals to hunt. 

The female typically lays 2 or 3 eggs and the incubation is almost exclusively taken care of by Mom. The male will bring food to her while she’s tending to the eggs. Mom takes care of the young for the first 1 to 2 weeks after hatching and the male continues to deliver food for her and the young. Mom gets a break once the babies are a little older when Dad pitches in. At 5 to 6 weeks, the young are able to fly.

Almost all Broad-winged hawks migrate in the fall to Central and South America. A great place to see these raptors as they make their way south is at Smith Point on Galveston Bay’s eastern shore. Smith Point features a land form that funnels the birds into a migration corridor. At peak migration periods, thousands of birds can be seen in one day. Broad-winged hawks make up approximately 70% of the birds traveling this route.

Beginning on August 15th and running through November 30th, the Gulf Coast Bird Observatory keeps a daily raptor count at Smith Point called the Smith Point Hawk Watch. A watch tower has been constructed for this purpose and is open to the public from 8am to 4pm. Staff and volunteers are at the watch tower to talk with visitors and answer questions. There are scopes and binoculars so visitors can get a better view of the birds.
