Where are the MYWA's?

3-9 October

It has been a great week species-wise at the banding station. But all I can say is "Where are the MYWA's?" (the sub-species of Yellow-rumped Warblers we band called Myrtle Warblers). We've had a smattering of yellow-rumps but as this is our 11th fall season we've always had huge numbers of MYWA's coming in this week. Typically by now we are banding 150-300/week but 9? What? Rumor has it they didn't do that well on their breeding grounds, so I'm curious if any banders can verify that. On the other hand, as I said last week, Blackpolls did have a good year and we can attest to that with another 29 banded this week.

This past weekend a large covey of Northern Bobwhite were released on the island to try to establish a population of quail. This has been done for the past three years but most have not survived. On Monday as Gracie (our banding dog) and I walked through the field out to our nets on the bluff we ran into the covey and explosion of quail ensued! We've encountered them all week and some have ended up in our nets such as this HY female. Females have buffy coloration on their throats and males have white throats.

We ended up handling 22 species of birds on the 3rd including another American Redstart, 2 more Blue-headed Vireos, pictured below and always a pleasure to handle, although they can be a bit nippy,

12 more Blackpolls,including an adult male with heavier and thicker black streaking on the body than it's HY counterpart


 and our first Black-throated Green Warbler of the season.

We banded four more on the 7th. Our 2nd Northern Parula was banded on the 3rd,  a HY male this time.

 Males have a distinct tawny and slate-colored band across their breast not seen in females, although adult females can have a tawny wash.

Our best bird of the day was a HY male Connecticut Warbler as we only band one or two a year.

Rainy days prevailed both Tuesday and Wednesday so we were unable to band. We did get back out in the field on the 6th although it was a cool and windy day. Surprisingly we handled 105 birds with many of our northern birds showing up this day- Slate-colored Juncos, White-throated Sparrows, Golden-crowned Kinglets (18 in all), a hatch year female shown below,

20 Ruby-crowned Kinglets with a HY male shown below,

four Brown Creepers,

 a Hermit Thrush

 and a Winter Wren,

a species we haven't handled since 2008. They are such small and adorable birds with their tiny tails.

We also banded a few Myrtle Warblers and a Nashville Warbler. On Friday the 7th we added an adult Red-winged Blackbird to our list

and a HY Eastern White-crowned Sparrow.

The next day we banded an adult Eastern White-crowned Sparrow,

a HY female White-breasted Nuthatch,

and were very pleased to band two more warbler species, a HY Tennessee Warbler with it's very pointy beak, white undertail coverts, green back, dusky eye line and yellowish supercilium,

and an Orange-crowned Warbler with it's indistinctly streaked breast,
 

yellow undertail coverts,

and concealed orange crown patch present on this young male.  

We had a Song Sparrow with an unusual  extension of feathers on it's tail shown below growing off the end of a feather the bird was replacing. It was a hatch year with fault bars evident across some of the feathers.

As always, a big thank-you to those helping this week- Jo-Anna Ghadban, Gretchen Putonen, Juliet Lamb, Carolyn Kennedy, Becca Miller, and Judith Bruce.

Rest of September

I've been unable to post as often as I would have liked due to taking care of an elderly parent, so I'm posting the last 3 weeks of September here. I'll break it up week by week just as I would if I was posting separately. Our best week was the last week of September when we had many species (39). Rain occured most of the first week and I missed out on most of the second week due to moving my mom out of her apartment and into an assisted living facility.

9-11 September

The second week of September was still rather quiet for this time of year migrant-wise. A meager 22 birds were handled on the 9th, but the highlight of the day were two Yellow-bellied Flycatchers.

A SY Song Sparrow was recaptured that still had a brood patch. She hadn’t yet begun to molt and her feathers were so worn she appeared to have abnormal black feathers when in reality it was the wear that gave the odd appearance. The pictures I took didn't demonstrate this well but you get the idea.


Another HY Song Sparrow was replacing half of it’s tail, giving a good example of the difference between thinner and more pointed outer tail feather compared to the rounder outer adult tail feather on the right.


Finally our numbers increased substantially on the 10th capturing 88 birds, one being  a HY Eastern Phoebe that had finished it’s first prebasic molt,

 replacing the inner greater coverts, but retained the outer two smaller, buff-edged outer greater coverts.

This HY male American Redstart had more yellow streaking on his breast than I’ve seen before.

Our first Western Palm Warbler, with it’s shorter tail, beige supercilium and breast came in on the 10th too.

The highlight of the day was a Mourning Warbler.

On Sunday 11 September a banding demonstration was held for the public. Approximately 41 people attended. We handled 65 birds of 17 species of birds including Yellow-breasted Chat, always an impressive bird, Baltimore Orioles, Ovenbird, Prairie Warbler,

Hairy and Downy Woodpecker, Red-eyed Vireo, chickadees and titmice, goldfinches, Common Yellowthroats, Eastern Towhee, Carolina Wren, House Finch, Song Sparrow, of course MANY Gray Catbirds, and our earliest ever Brown Creeper!


One of the Gray Catbirds recaptured this day turned out to be originally banded as an After Second Year  from the Punkhorn in 2009 during one of our MAPS banding days, making it at least 4 years old . We've recaptured numerous birds on Wing Island originally banded in the Punkhorn.

Julie O'Neil who works at the museum, took this picture of our 'band' of merry men (or should I say women!). Pictured left to right- Jessica Remple, Gretchen Putonen, Sue Finnegan, Carolyn Kennedy, Judy Keller, and Judith Bruce. Another one of our 'regulars' Jo-Anna Ghadban couldn't make it.

Many thanks to those above for helping this week, also Judy Fenwick.

17-21 September

We got out 5 days this week. Two more Warbling Vireos were banded on the 17th

another Mourning Warbler (19th),

and we had our first Black-and-white Warbler of the fall grace us with her presence on the 17th. She was a HY with a pale buffy face

and a molt limit in the alula feathers. Her second alula feather showed only a trace of white edging, which would show white on both sides of the feather in an adult.

Our first Wilson’s Warbler came in on the 20th,

 a first year male sporting an extensive black cap but with green edging indicative of first year birds.

We also captured a female adult Eastern Towhee with her brilliant red eye.

Compare it to a brown-eyed first year towhee. By the spring her eye will be red too.

Another first of the fall season for us was a Lincoln’s Sparrow on the 21st with it’s delicate streaking on both the breast and throat.

I certainly was expecting more in the way of migrants this week adding only 3 new species since the week before. It could be the northeast winds at the beginning of the week pushed the migrants further inland and few migrants come through on south winds we experienced at the end of the week. The last of the Ruby-throated Hummingbirds was captured on the 19th and I don’t expect to band anymore on Wing Island this year. Capture rates of all species were low too for this time of year with an average of 33 birds per 100 net-hours.

Thanks to all who helped with the banding sessions during the five days: Jo-Anna Ghadban, Gretchen Putonen, Carolyn Kennedy, Arthur Driscoll, and Mike Quinlan, a visiting bander from Maryland.

25-28 September

Finally! The nets were hopping this week. We had a nice variety of birds with northwest winds most of the days pushing migrants through our area. Rainy days prevailed between the 22nd -24th and I fully anticipated getting skunked on the 25th too and had cancelled banding the night before, but was pleasantly surprised when the rain had blown out and we could get out. The best day for numbers was on the 25th with 105 birds captured, but we had the most species variety on the 26th – 26 banded species for the day.

On the 25th we captured all three of those confusing fall warblers often mistaken for one another; Bay-breasted,

with grayish legs and a hint of rust coloration on the flanks,

a HY male Pine Warbler

with its unstreaked back,

and numerous Blackpoll Warblers, a HY male shown here with black feathering on his face, throat, and breast.

 Our first Myrtle Warblers came in this day too (3 of the hundreds I anticipate will show up in our nets this year), all first year birds.

Blackpoll Warblers appear to be having a good year. By the end of this week we had already banded 38 birds and expect to band more in October. Our average number of Blackpolls over the past 10 years is only 18 birds/year so I’ll be curious to see how many we actually get when our season is over. Another regular in our nets this fall are Yellow-breasted Chats with 10 banded birds so far.

An additional first for fall on the 25th were 2 White-throated Sparrows.

What a great day the 26th was! We had a foggy start but that soon burned off and the day turned out to be lovely. It proved to be a good migration day. It was a hard call to pick our best bird of the day. Was it the Blue-headed Vireo with his beautiful plumage and white spectacles?

Or maybe it’s cousin, the more subdued Philadelphia Vireo, a species we don’t band that often?

Notice the almost non-existent last primary feather (p10) on the outer edge of the primary coverts, a good key to differentiate it from a Warbling Vireo. Occasionally we get very bright Warbling Vireos and dull Philis.

But then again the best bird could have been the Gray-cheeked Thrush!

Although for me I think I’ll give it to the Yellow-billed Cuckoo, only the 3rd one we’ve ever banded at this site, a handsome HY bird growing in new tail feathers.

We had many nice birds this day but those that had their pictures taken included our first of the season Indigo Bunting, a HY female with just a hint of greenish-blue color in her wing,

a HY male Nashville Warbler,

our first of fall HY Magnolia Warbler

and another young male Wilson’s Warbler.

On the 27th we banded a young female Wilson’s Warbler, lacking a black cap,

a HY female Northern Parula,

and a Swainson’s Thrush with its buffy eye ring compared to the Gray-cheeked from the previous day.

We had two unfortunate young birds with pox on their mandibles causing deformities. A Gray Catbird missing part of it’s lower mandible on the 26th,

and a male Common Yellowthroat missing part of it’s upper mandible.

Numbers of birds lessened a bit on the 28th, but we did capture another Black-and-white Warbler, Yellow Palm Warbler, more Myrtles and Blackpolls and our 3rd Mourning Warbler, a HY male.

Thanks to Jo-Anna Ghadban and Gretchen Putonen for helping this week. Due to a weekend getaway I won’t be able to get out into the field again until October 3rd provided the rain holds off.
