April 21 and 22, 2015 WARBLERS!

FINALLY!  Today started out hot and humid but also with the sounds of many chipping birds.  A thunderstorm yesterday and a shift of winds and we had warblers to see and band.

Today was record breaking - we banded 26 birds and all of them were warblers.  There were 11 species noted on the property and we managed to catch 7 of them.

First it was a run of Ovenbirds.  We eventually banded 8.  The second photo shows the lighter tips indicating a bird that was born last year.

The birds kept coming and coming.  We caught a Common Yellowthroat and a Black-and-white Warbler at the same time.  Currently I do not have a photo of the Common Yellowthroat from today. It was a male.  We eventually banded 4 Black-and-white Warblers.

It seemed like most of the Ovenbirds took off or at least found a place to hide.  We started getting Worm-eating Warblers and Black-throated Blue Warblers.  All this time, between bandings, we were seeing many warblers in all of the ficus/strangler fig trees as well as in the oaks.  Frustrating to have so many birds so high.  We banded 3 Worm-eating and 7 Black-throated Blue Warblers.

At times it seemed like birds were flying in.  We started to see a few more American Redstarts.  We banded 2.

The bird that topped it all off for me was finally (in our third spring) catching a Cape May Warbler and a stunning male at that!  This is the 99th species I have banded.

The other 4 warbler species present on the property today were Blackpoll, Prairie, Palm, and Northern Parula.  Only the Blackpoll is a species I have yet to band.

If weather/time/personnel permits we will band for a while tomorrow.  Hopefully the birds will stay and fatten up before continuing their journey.

(UPDATE 4/22:  It seemed about half of the birds had moved between yesterday and today but we still had a good day. We banded 3 American Redstarts, 4 Black-throated Blue Warblers, 1 Common Yellowthroat, and 4 Ovenbirds.  That would usually be a great day.  We also noted 2 migrants on the property that we had not seen yet this season - A Scarlet Tanager and a Red-eyed Vireo.  Also present was a Black-throated Green Warbler, bringing the two day warbler total to 12.

Next regularly scheduled banding will be April 28.  Nets go up at 6 am.

April 14, 2015

Many apologies for the delay in this post.  On April 14 we banded 2 Gray Catbirds and a Northern Cardinal.  We also recaptured one of each of these species.

The Northern Cardinal is the only one we managed to photograph.  Pete and Nancy P are making great progress extracting and banding.  Pete banded this Northern Cardinal and Nancy banded the catbirds.

Migrants were non-existent.  Winds from the south send birds straight over without stopping.  Good for the birds but not as good for the banders.  That's actually fine with us.   May the birds make good progress to their nesting grounds. We still manage to have a good time and survey the property.  The Yellow-crowned Night-Herons are nesting as are the Red-shouldered Hawks.  There was no evidence of a brood patch on this female cardinal but maybe soon they will nest.  We did hear a Brown Thrasher which are not typically on the property and may have been passing through.  

I forgot to mention that last week Diana observed a snake entering a Red-bellied Woodpecker nest. We can only assume the chicks or eggs were eaten.  Nature in real life or real life in nature.  True either way you look at it.

Next banding session will be April 21.  Nets go up at 6:15.

April 7, 2015

The bad news is that the weather is terrific and we just might be anticipating migration that is yet to come.  Tuesday was quiet but we did manage to catch 4 Gray Catbirds.  That number is high considering that not many spent the winter on the property.

We also recaptured another Gray Catbird and a Northern Cardinal.  The cardinal had been banded over a year ago.

We spent a lot of time birding the property and enjoyed the sounds of returning Chimney Swifts and more Cedar Waxwings than we have had all winter.  The only warbler was a singing Black-and-white Warbler.

Next session:  Tuesday, April 14.  Nets go up at 6:30 am.

March 31, 2015

Could today have been any better???  Yes, I suppose we could have banded more birds.  I told the crew to be ready for early migrants like Hooded Warbler which we have banded in the past.  I told them to keep the nets low for these ground-dwelling birds.  We did see a few migrants.  But, we didn't catch any Hooded Warblers.  (Is the suspense getting to you yet?)

Today we banded a first for me, a life bird for some, a property first, and a bird not seen in the county in years.  A Louisiana Waterthrush.  Since Northern Waterthrushes and Louisiana Waterthrushes are so similar, one must take care with the ID.  Measurements, field marks, the absence of a dark undertail covert, and a long bill all supported this identification.

The red arrows show the mostly unmarked throat and the unmarked undertail coverts but the key was the bill length which was well beyond the normal range for Northern Waterthrush.

So, disappointment could have been the theme of the rest of the session but Pete Grannis discovered a perched, adult Eastern Screech-Owl and Diana Doyle soon found the 3 young.  Jean saw the 4th young so we had FIVE owls.  What a team even when it comes to finding birds.  I love this aspect of our group and our study.

We also recaptured a Painted Bunting and a Black-throated Blue Warbler (banded 3 weeks ago).  It wasn't a session with a lot of birds but I don't recall anyone complaining!

Next session April 7.  Nets go up at 6:30 am.

March 24, 2015

This session was much busier than the last few weeks but still only a hint of migration.  Florida migration is very weather dependent and we had hoped that west winds would drop birds.  There were a few but first off we were in for a big surprise.

Our first bird in the net even before first light was an Eastern Screech-Owl!

I was thoroughly amazed at how calm the bird was.  I expected to be grabbed or bit.  Neither happened.  The owl was not very tangled so release was fast.  We got a few photos and then released the bird unbanded.  We did not have the proper size band.  The bird sat on my hand for longer than I expected and then quietly took off into the dawn.  Amazing how light this bird was.

After such a beginning we captured two migrants.  It is so rewarding to read that a certain species is on the move and to then capture some.  We banded two Common Yellowthroats.

Also captured today was the same female American Redstart that was banded in the March 19, 2013 that we also caught on March 3, 2015.  Not sure this is the same female but it is a photo of one we captured on that day.

Also captured were 2 Gray Catbirds and a Painted Bunting (green - female or first year male).  All in all a nice day.

Next session:  Tuesday, March 31.  Nets go up at 6:30 am.

March 17, 2015

One truth can be stated - migration is underway but we cannot prove it at the station as of this session.  Several notable birds were seen this week at Possum Long but not in the nets.  For several important reasons, we did not set up all of the usual nets.  We also did not have any captures.

Diana found a new bird for the property:  an Orange-crowned Warbler.  Below is a photo of one we banded in January, 2014 at Lakeside Ranch Stormwater Treatment Area.  A Black-and-white Warbler was also around and it would be hard to tell if this one was around all winter or had newly moved onto the property.

The presence of a newly banded Black-throated Blue Warbler is exciting as it supports the theory that birds that are low in fat remain around to fatten up for the rest of their journey.

Chimney Swifts were detected.  They are a summer resident and one of the early signs that migration is underway.  Yellow-throated Vireos are now being seen.  This is a species we detected on the property in early March last year.  Hopefully weather and movement will combine for a busier week next session. 

Next session will be March 24.  Nets will go up at 6:15 am.  All are welcome.

10,000 hits!!

First off I would like to thank all of the followers of this blog for their interest.  On March 9, somewhere around 1:30 we passed 10,000 hits to this blog.  We do this study for its primary purpose of determining the status and distribution of birds (what birds, when) but one of my goals is sharing and education.  THANK YOU!  Today also marks our 100th post.

We banded 2 new birds and recaptured 4 at Tuesday's session.  In studying the above mentioned status and distribution, we expected more Gray Catbirds this winter.  Obviously there was something different this year.  There were many fewer catbirds than the past 2 winters.  We did band 1 new one and recaptured one we banded in the fall.

Our other new bird was a Black-throated Blue Warbler.  Yay - migrants are beginning to move.  This was a male born last summer.  The white speckling on its throat indicated this.

The other recaptures were 2 color banded Painted Buntings one from last December and one from this February.  We also had a male Northern Cardinal that was born last summer and banded in September but now looks like all the other adults.

We also monitor birds on the property.  The nesting Osprey is a big draw for visitors and everyone awaits the appearance of the young.  Though Osprey are common, it is special to see its life played out in front of our eyes.

Next banding session:  Tuesday March 17.  Nets go up at 6:15.  Visitors are welcome at any time but most birds are typically caught in the first few runs.  (Of course if there are many migrants, this could be proven wrong!)
