Tuesday at Possum Long was better with the arrival of more Yellow-rumped Warblers.  We banded 4 of them in addition to a Black-throated Blue Warbler, 2 Gray Catbirds, and a Northern Cardinal.

Since we have been banding near the pond at Possum Long, several folks wondered if there were more birds back at our "woods" net.  This area is our best area for numbers and diversity.  No coincidence that it is densely vegetated and has pretty good ground cover.

So, we returned to Possum Long on Friday to test the theory.  It did pay off.  We banded 2 Painted Buntings (known for their love of cover), 2 Gray Catbirds, and an American Redstart.  We also recaptured the Carolina Wren that was one of the first birds we banded this fall.  We could not get all of the bird's measurements then as it was molting.  It is now fully feathered and we collected all of the typical data.

On Sunday we revisited PB 1.  Though there were quite a few birds attending the feeders, it was a bit windy and we only caught 3 new buntings and recaptured one from last spring.  It had been banded as a young, green bird and it remained green so we now know it is a female.

Grand total of Painted Buntings to date is 45.

Next scheduled banding at Possum Long is November 21.  Nets go up at 6:30 am.

November 4, 5, and 7, 2017

Things have really slowed down yet we are still catching a few new birds.  We banded at PB 32 on Saturday and at Possum Long on Sunday and Tuesday.

Painted Bunting sessions will become more of our entries over the next few months.  We will continue at Possum Long until early December but will be taking a break over the holidays.

Our return trip to PB 32 was productive.  We banded 2 new buntings and recaptured another.  It is always great visiting with our hosts.

On Sunday we tried setting up at the pond at Possum Long.  Unfortunately the water is high so we cannot span the water as we have in the past.  We did manage to catch a Painted Bunting, 2 Gray Catbirds, a Common Yellowthroat, and an Eastern Phoebe.  Eastern Phoebes are winter residents and we rarely catch them.

At our regular Tuesday session we again caught Painted Buntings, two of them.  The good news is there seem to still be some banded and unbanded ones around.  Maybe they are still arriving??  We also caught a Common Yellowthroat that had been banded last year.  Nice to see some site fidelity in that species.

The next regularly scheduled Possum Long banding will be on November 14.  Nets go up at 6:15.

Tuesday banding at Possum Long was much busier this week but the migrant birds have mostly moved through.  It is really hard to predict which ones will stay and over winter and which ones are still moving through.  We had a lot of Gray Catbirds on the property.  We banded four.  We also banded three Painted Buntings and recaptured another one from last spring.  I believe the population is increasing on the property.

We also banded one new Palm Warbler and a Black-throated Blue Warbler.  There were quite a few recaptures (Ovenbird, Black-throated Blue Warbler, American Redstart, Gray Catbird).  Most had been banded within the past month.  Comparing fat now to when they were banded was concerning.  Most had not gained fat.  Maybe they will just over-winter.

Since I didn't get any Painted Bunting photos from this session I am posting a photo of a male we banded at PB 61 on Sunday.

Who is on the Osprey pole?  During the last few sessions at Possum Long I heard that the following happened but I didn't get the photos until yesterday.  

Who is on the Osprey pole?

We have had recent flyovers of Egyptian Geese; a recently established exotic in Florida.  I never expected them actually be on the property.  I have seen Canada Geese on Osprey poles before.  They roost there until the residents return.  Must be safe up there.  I was glad to finally get a photo of this.

Megan has been volunteering with us for the past few months.  She has such great enthusiasm and drive to learn and help.  She banded her first bird this session.

Next scheduled banding session is Tuesday, November 6.  Keep in mind the time change.  Nets go up at 6:30.

October 21, 28 & 29, 2017

Tuesday was very quiet compared to other migration days.  It turns out that Wednesday would have been ideal but we were unable to band.  Likely from now on things will be quieter but maybe we will still have some surprises in store.  The weekend had a few!

At Possum Long we banded three birds.  A Black-throated Blue Warbler, a Red-eyed and a White-eyed Vireo.  Those birds made it a good day.  We also saw the Scissor-tailed Flycatcher again and were very surprised it was still present.  Happiness all around.

On Saturday, we returned to PB 46.  We banded a total of 9 Painted Buntings and had a recapture from a previous season.  These recaptures are giving us very good longevity and site fidelity data.

For incidental captures there we were surprised to have a Magnolia Warbler.  There have been more of this species captured this season than any other.  We also had a Blue-gray Gnatcatcher and a Blue Jay.

On Sunday we returned to PB 61.  We banded a total of 11 Painted Buntings and recaptured 3.  All three had been banded in March, 2016.  This means that they had flown up to their breeding places and back two times since being banded!

Incidental captures gave us another Blue-gray Gnatcatcher.  This is one of the smallest birds we band.  They weigh just over the weight of a nickel.  We also banded a Cape May Warbler.  Third for this season and only the fourth ever!  Note gray cheek with pale area under it.

Our season total of Painted Buntings now stands at 32.  

Next banding session is Tuesday, October 31.  Nets open at 7:30.

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.

The last day of this 4 day marathon was relatively quiet yet exciting.  We recaptured a Northern Mockingbird that we had banded almost exactly one year ago.

Northern Mockingbird

We banded a total of 6 new birds:  1 Black-throated Blue Warbler,  1 Black-and-white Warbler, 1 Red-eyed Vireo, 1 Northern Cardinal and 2 American Redstarts.  It was the redstarts that held the excitement.  

Black-and-white Warbler

Typically a female or young male American Redstart has yellow coloring and a white underside.  The second one we caught was distinctly different.  There are color variations in most species.  Many times it is a lighter color, partially white, or entirely white birds.  There are also differences in many yellows and reds.  In this case the bird was distinctly blacker than normal.  This is called melanistic.  We are waiting to hear more about this particular bird.

American Redstart - melanistic

We are setting up for a banding event on October 21.  Young birders in grades 3-6 can come view our station.  We will post results.

The next scheduled banding session will be held on October 24, 2017.  Nets go up around 7:15 am.
