October 21, 2017 hosting Young Audubon

Saturday the banding station hosted a Young Audubon event for Audubon of Martin County.  Eight students in 4th, 5th, and 6th grades came to learn about bird banding.  They got to see birds, banding techniques, nets, and most of the aspects of banding smaller perching birds.  We talked about what can be learned from bird banding.  We did two exercises to understand a bit of the science.

A popular exercise was "how many at your feeder"?  Hershey miniatures representing 1 bird species came and went from a "feeder".  There were never more than 4 out at any one time.  When asked how many birds, the students realized that only 4 had appeared at any one time but that no one was sure if they were all the same.  The exercise was repeated with marked "birds".  It was quickly apparent that 8 birds had been seen but never more than 4 at a time.  The chocolates were then devoured.

We also repeated an exercise where a small stick is gathered to represent a bird leg.  They are measured with a leg gauge to determine band size.  Each one was told a bird species that had a leg that size.  They also used cut straws to color mark their bird leg.  We were fortunate to recapture a color banded Painted Bunting which really illustrated this activity.  They learned that the position of the colors determined a unique combination for each bird.

We banded a total of 14 birds and recaptured a few.  We had 1 American Redstart, 1 Blue-gray Gnatcatcher, 1 Common Yellowthroat, 1 Palm Warbler, 2 Black-throated Blue Warblers, 1 Ovenbird, 2 Red-eyed Vireos, and 5 Gray Catbirds.  Some of the students were able to release birds.  They enjoyed comparing their size band from the measuring exercise to the real ones we used.

It was such a busy event that there wasn't always time for photography but here are a few photos:

Excitement for the day, besides the birds banded and sharing our project with students, was the presence of a new bird for the Possum Long property.  Robin spotted an amazing treat for all present!  Totally unexpected was a Scissor-tailed Flycatcher in the top of the large ficus tree.  Typically this species feeds over fields from low trees, power lines, or fences.  The majority of its diet is large insects like dragonflies and grasshoppers.  This bird was actually observed eating the figs from the ficus tree.  I only knew of one other instance of this species in Martin county.  There are sometimes small numbers of them in open areas in western St Lucie county over winter.  This seems like an early arrival.  It is not expected to stay in the area.

Next regualrly scheduled banding is on October 24.  Nets open at 7:15.  If it is raining hard the session will not be held.
