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.

Sunday was a gift to birders and banders.  We banded a total of 21 birds of 12 species.  We saw 11 different kinds of warblers as well as many other migrants.  Remember you can see bird lists of this site on eBird.  Explore hotspots, type in Possum Long, view recent lists or all sorts of other data.

Many of the birds we banded were warblers:  1 American Redstart, 1 Magnolia Warbler, 1 Northern Parula, 1 Common Yellowthroat, 3 Black-throated Blue Warblers, 1 Ovenbird, and our best bird of the day.

Our best bird was a real surprise as they are tree-top lovers so we rarely catch them and also because in the fall they typically migrate more offshore.  Fall Blackpoll Warblers do not look like the "chickadee look-alike of warblers"  they are more streaked and yellowish.  However their feet still have bright soles.

The other 12 birds banded were 2 Red-eyed Vireos, 5 Gray Catbirds, 1 Northern Cardinal, 3 Painted Buntings (YAY!) and a Blue Jay.

Continue to view the next 2 days.  Update for next session is on the October 17 post.

October 7 & 8, 2017

Sometimes, especially during migration, we elect to band on days that are not at the regularly scheduled time.  We banded on both Saturday and Sunday this week and it was well worth it.  We are at the peak arrival for some of the birds.  Saturday was warbler day.  We banded 22 individuals representing 8 species of warblers.  The expected American Redstarts (3), Ovenbirds (2), and Black-throated Blue Warblers (9) did not disappoint.  We even caught one each of two less commonly caught warblers - Northern Parula and Black-and-white Warbler.  But then there were 3 highlights!!

Highlight One was catching more than one Magnolia Warbler!  We have never caught three in one session before.

Highlight Two was catching a first for Possum Long Banding.  Though Yellow-throated warblers are sometimes seen on the property, we had never banded one there.

Highlight Three was catching not one but TWO Cape May Warblers.  In all of the other years we have banded we had only caught one of these.  Two on one day is pretty awesome.  Cape May Warblers are also typically too high in the trees to catch them.  In areas where there are not tall trees, these bird can be seen down low but they prefer the upper areas in the trees of Possum Long.

Two Cape May Warblers!!

So in addition to the 22 warblers on Saturday we also banded two Painted Buntings and a Red-eyed Vireo.  The vireo was an adult with a really red eye as opposed to the two younger birds we caught recently that had dark eyes.  

Red-eyed Vireo

On Sunday we caught half the number we did on Saturday and the bird diversity on the property was much different, yet it was still a productive session.  There were still Summer and Scarlet Tanagers around and several Red-eyed Vireos.  The surprise was seeing THREE Baltimore Orioles.  We did not catch those but once again, Black-throated Blue Warblers (4) were the majority of the birds caught.

Other birds caught were 2 American Redstarts, a Black-and-white Warbler, a White-eyed Vireo, an Ovenbird, 2 Swainson's Thrushes, and a Gray Catbird.  Gray Catbird numbers should be increasing in the next few weeks.

Thirty-seven birds in two days!

The next regularly scheduled session as announced on the previous post is on October 10, 2017.  Nets go up at 7:15 am.

September 30 and October 1, 2017

We did a little extra banding this weekend since it is migration time.  We banded at Possum Long on Saturday and at PB 46 on Sunday.  Saturday was productive but a bit slower than last Tuesday's session.  We banded 13 birds (8 species) and saw a few that went no where near the nets.  These were the first of season Cape May Warbler, several Scarlet Tanagers, a Northern Parula, and a Summer Tanager.

We banded 4 Black-throated Blue Warblers, 3 Ovenbirds, and one each of Red-eyed Vireo, Carolina Wren, Swainson's Thrush, Gray-cheeked Thrush, Northern Cardinal, and Gray Catbird.  Of these the thrushes made their first welcome appearance.  We should get more this month.  The Red-eyed Vireo was a young bird so it did not yet have a bright red eye.  It was the fifth one of this species for the property.  The Carolina Wren was only the second one on the property.

At PB 46 we were pleased to catch some of their early Painted Buntings.  They estimated they had at least 10-15 birds back.  Three were previously banded.  We caught 5 new green Painteds.  we used our new split band - so be on the lookout for yellow/light green bands.

One of the buntings was a very young bird.  Just out of the nest Painted Buntings, both male and female, are green and brownish.  They molt in the fall like the adults but ALL of the youngsters stay green.  They do not molt much until the next fall (about 15 months) and this is when the male birds acquire their pretty colors.  

Earlier in the season, these hosts had a 2nd year male bird starting to grow in the bright feathers.  We had received other photos just before Bob sent this one.  It is the first time we had photos of this particular change!!

Back to the youngster, you can see in the photo below that it was heavily molting and that it still had some of the juvenal brownish feathers.  (Arrow)

We also caught another Red-eyed Vireo as well as several Blue Jays, several Common Grackles, and a Northern Cardinal.

We will band at Possum Long tomorrow, October 3.  Nets go up at 7 am.  It could be windy so hopefully the more sheltered nets won't blow.  If they do, we will close early.

September 27, 2016 It's here and may it continue!

After a great day migrant birding in Fort Lauderdale on Saturday, Bill and I did an impromptu session at Possum Long on Sunday (9/25).  Though we did not catch a lot (Ovenbirds and Northern Cardinals), the birds on the property, high up in the canopy, were fantastic!  Probably my second best day ever at Possum Long.

Young male Northern Cardinal

We found 23 species of birds including one property record.  The two Baltimore Orioles we saw may not be the first ever there but it is the first we are aware of.  Chimney Swifts were flying over.  We found a Yellow-billed Cuckoo.  Ruby-throated Hummingbirds are back.  We had six species of warblers:  Ovenbird, Worm-eating, American Redstart, Northern Parula, Black-and-white, and Pine.  Bill flushed a Chuck-will's-widow and it landed long enough for me to see it.  There were several Summer Tanagers and a Brown Thrasher!  I couldn't wait to go back Monday.

On Monday, there seemed to be fewer birds and different ones.  I did find 2 additional species of warblers:  Cape May and Prairie.  One of the orioles remained as did the Brown Thrasher.  Red-eyed Vireos were evident.  I had a pretty good list considering I only had an hour to look.

So, Tuesday morning found me hopeful but I was worried that only 5 nets might not be enough to catch birds.  I would never do more than I thought I could safely handle alone.  When what to my wondering eyes should appear but Nancy Price, returned from her grand adventure with greetings from Jane!  I am so thankful she was there to help.  We added more nets and hoped for the best.  It was decidedly quieter than Sunday but migrants were around.  Even George had migrated back from Nova Scotia!  First Nancy brought me a Swainson's Thrush - first thrush since spring.

Not many birder's get to see the light band on the underwing of this species.

We caught two hatch year Northern Cardinals but they went unbanded as I didn't have the proper size band (waiting for an order to come in!).

Next we caught a White-eyed Vireo.  This is a young bird that has yet to develop that pure white eye.

These birds can look a bit intimidating.  They are assertive birds and tell you so!

Right after the vireo, Nancy brought in a Black-throated Blue Warbler.  Also a young bird as told by the white patch on his throat.

Last but not least we got one of the many Red-eyed Vireos on the property today.  This bird was also young, the eye had not fully turned red.  You can just about make out the hook on the beak typical of many vireo species.

All in all a day I was very happy with.

Next scheduled banding:  Tuesday, October 4.  Nets go up at 6:45 am.
