Vireo at Kiptopeke

This bird, injured or ill, was at the Kiptopeke Hawkwatch on Oct 18th. Photos are posted here, back, side, front and head close-up, so that others may send opinions to taberzz@aol.com

The features of Cassin's Vireo and Blue-headed Vireo make this identification challenging. Key features include the head and back color, throat/malar contrast, lores and supraloral coloration and definition. Yellow on the sides is variable in both species. One researcher so far, with access to museum study skins, has done an evaluation and thinks the features point to Cassin's.

Monarch Migration 2019 Recap

Hello, I’m Michael Ferrara, CVWO’s Monarch Biologist for this year’s fall migration. Some of you may remember me from last year and from seeing me throughout the past two months. Since the end of last season I spent 6 months leading a crew in southern Texas conducting small mammal trapping and bird surveys. I was happy to be back this season to conduct the Monarch surveys and to assist Megan and Anna at the platform. This year there were a few changes to the Monarch protocol, since the Hawk Migration Association of North America added a Monarch tally on our hawkwatch page and I conducted a point count at the Eastern Shore of Virginia National Wildlife Refuge.

This season was quite a bit different than last year. The peak of the migration moved through during early October and unfortunately there were only a couple of days with a ton of Monarchs. The largest number of Monarchs I tagged in one day was 150, but there were only 2 or 3 days in which I tagged over 50 Monarchs. There were a few days in which a lot of Monarchs were seen from the platform but unfortunately they did not land. In total, I tagged 761 Monarchs this season. The majority of them were seen around the Hawkwatch platform.

This year the Monarchs were observed roosting at the roost site by Wise Point. They weren’t seen in historically large numbers, but there were more observed roosting than last year.

In the Kiptopeke Butterfly Garden, we recently had Monarch caterpillars chowing down on the milkweed growing in the garden. Our milkweed has grown over the past year and now we have enough to support a bunch of caterpillars. Along with Monarch caterpillars, Common Buckeyes, Cloudless Sulphurs, Red Admirals, Sleepy Oranges and Clouded Sulphurs have been some of the frequent visitors to the butterfly garden.

I believe that the dry summer has hampered the blooming goldenrod and mistflower, reducing the nectar availability for the Monarchs. The Monarch migration for the eastern flyway was forecasted and ended up being a weaker year this year. Fortunately, this year has been a great year for Monarchs across most of the country. Now that the weather has dropped and there have been a few frosts the migration has stopped through the Eastern Shore, but it is still possible to catch the occasional late Monarch.

November Surprises and Rarity Roundup

November is always an interesting month at the hawkwatch platform, and it can be hard to predict what kinds of interesting species may make appearances. Diurnal non-raptor migration has been picking up, and we've been noticing flights of Tundra Swans, Snow Geese, Common Loons, Great Blue Herons, Red-winged Blackbirds, American Robins, and more. So far, the season high day count for Tundra Swans was 79 on November 3, and the high day count for Snow Geese was 76 on November 17. We are often alerted to the presence of geese and swans as they call while migrating overhead. This beautiful sound can also be heard at night sometimes.

On October 29, a Merlin zoomed by the platform carrying a Yellow-rumped Warbler. While we often see Merlins carrying dragonflies, it's a less common sight to see one carrying a songbird. Steve managed to get some amazing shots.

On November 1, we set a new season record for Bald Eagles, breaking last year's previous record! It will be interesting to see if record-breaking flights continue for several seasons since this species is doing so well. Five Golden Eagles have also been seen this season so far, and we hope to find more soon!

It was interesting to see a nearly tail-less Turkey Vulture on November 2. On the following day, it was seen again (assuming that this was the same bird, based on photographic examination of the tattered tail). Turkey Vultures with partially or fully missing tails are a fairly regular occurrence at hawkwatch sites. Perhaps this has to do with molt, or maybe it results from squabbles with other scavengers while feeding.

Similarly, we have seen a young Bald Eagle with partially missing tail feathers. Maybe the feathers were chomped by an angry fish!

Also on November 2, an intermediate or dark morph Swainson's Hawk was seen far out on the east side. This normally western-ranging species occasionally strays to the east, and Kiptopeke often records one or several passing through each season. Due to the bird's distance we were not able to obtain photos.

That same afternoon, Don Metzger spotted a rather late Black-throated Green Warbler. This beautiful bird was flitting around and feeding in the Dog Fennel right behind the platform, which allowed for stunning views.

To add to the excitement of 11/2, we had the unique opportunity to watch a rocket launch from the platform! The Antares NG-12 took off from the NASA Wallops Island facility at 9:59 am, leaving a brilliant red streak across the sky to our northeast.

 As is typical in November, the Red-tailed Hawk migration has been picking up. So far, our highest day count for the species was 44 birds on November 9. It is always interesting to see the beautiful variation in this species. Some have almost no belly band, while others are heavily marked in different shades. Some are pale, while others have rufous tones on their bellies.

We have been seeing some likely "Northern" Red-tailed Hawks as the season progresses. It is difficult to identify these birds for certain, but they often have very darkly marked, blobby belly bands and dark throats. There is much variation in the subspecies, and intergrades are also possible.

We have been enjoying some beautiful views of Northern Harriers. Harrier migration is fascinating in that these birds may fly in any conditions (including rain, fog, and snow) and at any time of day or even night. Their migration is more extended than many of the other raptor species that we see here, and the peak is somewhat unpredictable.

Along with the spectacle of these movements, we have also had some rare visitors to the platform. On November 6, a Black-chinned Hummingbird visited the hummingbird feeders and was photographed. We noted a glint of purple on the bird's throat and rounded outer primary feathers. For photos, take a look at Shiloh Schulte and Benjamin Clock's eBird checklist.

On that same day, seven American White Pelicans soared right over the platform, in beautiful formation.

Resident Pileated Woodpeckers have been putting on a good show, sometimes flying low over the platform singly or as a pair.

Red-shouldered Hawks have been moving through in good numbers, and we have also had the chance to see a few perched birds in the area. Red-shoulders are often sit-and-wait predators, meaning that they like to sit on exposed perches while waiting for prey to pass by. This can provide some great photo opportunities, such as this beautiful adult that posed on a wire near the park entrance.

Both American Crows and Fish Crows have been particularly active this season, which has resulted in quite a bit of mobbing activity. Red-tailed Hawks are a frequent target, such as this unlucky bird.

We have been noticing a very large number of Brown Pelicans hanging around the concrete ships this season. On November 8, Harry Armistead (who has been birding on the Eastern Shore for decades) even had a personal high count of 630 pelicans! It is nice to see that these birds are doing so well.

Almost every day lately, we have been delighted to see a Red Fox trotting past the platform. Foxes are common in the park, and there is a den visible from the Peregrine Boardwalk close to the beach. Keep an eye out for their tracks as you walk along the park's trails. Red Foxes travel in a direct register trot, which means that each hind foot lands precisely in the same spot as the front foot on the same side. As a result, fox tracks are often in a neat line (unlike the haphazard tracks of a domestic dog).

Held on November 9, this year's Rarity Roundup was a great success. During the annual event, birders from all over Virginia come to the Eastern Shore in search of rare and unusual bird species. A total of 57 people attended, with birders splitting up and covering different territories throughout Northampton County. A total of 155 species were seen, including several interesting rarities. A Brewer's Sparrow (only the second state record) was a huge highlight, spotted by Wes Teets at the Mockhorn WMA--GATR Tract. The bird hung around feeding with other sparrows for quite some time, allowing for great looks and photographing opportunities. Other sightings included Cave Swallows, Brewer's Blackbirds, an adult Northern Goshawk, and more.

The day after the Roundup, another hummingbird was spotted visiting the platform feeders. This bird was either a Black-chinned or Ruby-throated Hummingbird, and photos/video footage suggest that Black-chinned is a strong possibility. The primaries appeared to be rounded, and the bird was pumping its tail very often in flight; these are both typical characteristics of Black-chinned Hummingbirds.


It's been a wonderfully diverse November overall, and we hope to have plenty more interesting sightings during the next couple of weeks!

A Magical Week: Double Rainbows and Golden Eagles

Monday 10/21:

On Monday morning, I held a bird photography workshop for Birding Eastern Shore. It was so much fun discussing a topic that combines two of my passions: birding and photography. A big thank you to the Eastern Shore of Virginia National Wildlife Refuge for hosting this workshop! And thank you to Birding Eastern Shore for helping to organize this event, you were great students! Here is a link to the Eastern Shore of Virginia National Wildlife Refuge's and the Birding Eastern Shore's websites if you are interested in learning more about them. The refuge is an amazing place to visit, and Birding Eastern Shore is a wonderful group that helps visiting birders find the best places to see birds on the Eastern Shore. On November 6th, Anna Stunkel will be holding a bird drawing workshop at the refuge with Eastern Shore Birding. If you love art and birds, I highly recommend attending if you can!

At the Kiptopeke Hawkwatch, the week started off quite well with 157 raptors seen on Monday. A good number of the birds were accipiters, with 46 Sharp-shinned hawks and 44 Cooper’s Hawks. It was interesting that we had almost the same number of each accipiter species, since we tend to see more Sharp-shinned Hawks in general. We also had a decent falcon flight for this late in the season, with 10 American Kestrels and 19 Merlins.

Even though we are past the peak of migration, we are still seeing plenty of interesting travellers. We were amazed by how many large groups of scoter species were flying on this day, and Anna estimated that there were around 830 scoters total. In addition to scoters, we also saw 28 Great Blue Herons, 19 Common Loons, 3 yellowlegs species, and 1 Blue-gray Gnatcatcher.

Tuesday 10/22:  

This day was truly bizarre. The morning was very quiet, with almost no birds moving up until 11:30. All of a sudden, the skies cleared of clouds and birds started flying over very low. We had a really great view of a Red-shouldered Hawk that flew directly over the platform.

There were quite a few low flying Peregrine Falcons and Bald Eagles. We were lucky to witness a bald Eagle chase after an Osprey with a fish. The Osprey gave up fairly quickly and dropped the fish, which the eagle successfully caught.

The final raptor numbers turned out to be fairly good, especially with how slow it was in the morning. There were 104 raptors, with 8 Bald Eagles, 19 Sharp-shinned Hawks, 10 Cooper’s Hawks, 18 Ospreys, 23 Merlins, and 12 Peregrine Falcons.

At the end of the day, it started to rain and a Cooper’s Hawk visited the t-pole. As it sat there, a double rainbow appeared behind it! This hawk has been hanging around and sitting on the t-pole quite a lot. We are pretty sure it has been the same Cooper’s Hawk each time, so we have decided to call him Charlie. It was a perfect and magical way to end the day.

Wednesday 10/23:

We had our first two Golden Eagles of the season on Wednesday!!! They were pretty distant, since they were flying on the East Side. Many of the birds were sticking to a flight path on that side of the peninsula, likely due to the winds from the Northwest. It was also a very good day for seeing Bald Eagles and Red-tailed Hawks, since there were 22 and 19 respectively. There were 144 raptors in total, with 19 Sharp-shinned Hawks, 27 Cooper’s Hawks, 21 American Kestrels, and 17 Merlins.

Notable non-raptors of the day were 240 Double-crested Cormorants, 25 House Finches, 4 Killdeer, 3 Common Loons, 1 Blackpoll Warbler, 1 Nashville Warbler, and 1 Yellow-billed Cuckoo.  The Nashville Warbler and the Blackpoll were spotted by Anna early in the morning before I arrived, but thankfully I was able to find the Nashville again much later in the day to get a photo! It was hanging out with some Palm Warblers in the Dog Fennel field to the right of the platform. The warblers stuck around for a while, finding different insects to eat.

Pileated Woodpeckers have been zipping back and forth over the field that separates the different groupings of pine trees on the bay side of the platform. I was so pleased to finally capture the journey, and show off the beautiful white wing patches on this bird.

Thursday 10/24: 

After two (FOS) Golden Eagles on Wednesday, you would think that would have been the highpoint of the week. Except this exceptional week was not done surprising us. Partway through the day, a kettle of Turkey Vultures and one Bald Eagle started to fly over us. Thinking that this would be the perfect conditions… I blurted out, “come on Golden Eagle!" At that exact moment, Anna spotted a Golden Eagle rising up over the pines in front of us! The sheer coincidence felt almost like fate in that moment. We were ecstatic to be able to watch it fly so close to the platform. When most Golden Eagles are counted at Kiptopeke, they are spotted on the Eastern side of the peninsula. This particular beautiful bird was kind enough to circle over us for about four minutes.

Not only was it a lively day because of the Golden Eagle, but several of the raptors were acting very pugnacious. We saw multiple chases occur, including a Sharp-shinned Hawk and a Cooper’s Hawk, a Red-tailed Hawk that went after a Bald Eagle, and a very bold coop that went after a Peregrine Falcon AND a Turkey Vulture.

Birds weren’t the only interesting “gladiators” of the day. We had a dramatic battle for the corner of the platform railing between a Wheel Bug and a wasp. The wasp would continuously approach the Wheel Bug, pestering it until it would lift up its front legs and strike. The Wheel Bug attempted to catch the wasp several times, but right before it struck the wasp would take off. Both individuals moved on unscathed (although we continue to see a wasp visiting that particular corner of the platform almost daily).

We had 158 raptors on Thursday, but unlike Wednesday, the raptors main flight path was closer to the platform instead of on the East side. We had another good flight of raptors, mainly composed of 21 Bald Eagles, 30 Sharp-shinned Hawks, 44 Cooper’s Hawks, and 16 Red-tailed Hawks. There was a very large flight of non-raptors, with thousands of Yellow-rumped Warblers on the move, as well as a good number of American Robins and Red-winged Blackbirds. There were also 30 Eastern Meadowlarks, 30 scoters, and 15 Great Blue Herons.

Friday 10/25

The craziness of the week had to end at some point sadly. We had 40 raptors on Friday, although there were quite a few other types of birds on the move. There was an incredible flight of 95 Eastern Meadowlarks, 40 of which were in a flock together. Such a high number is very unusual at Kiptopeke. There were also 110 Common Grackles, 8 Cedar Waxwings, and thousands of Tree Swallows. 

Charlie the Cooper’s Hawk had a bit of fun chasing some crows around the recreation area. He took over the playground, and perched proudly on the slide. He has decided to stick around, since we have seen him (presuming it is the same male Cooper’s Hawk) perched on the T-pole at some point every day this week.
