The German harrier – some comments

HY male Northern Harrier, Milford, CT, USA (Julian Hough)

So, after looking at the images, here’s my thoughts on this particular bird:
  • eye-crescents look too white and bulbous, especially toward the rear of the eye .
  • the nape is perhaps not as dark, or solid as I might like, even though it appears somewhat hooded at a distance
  • the streaking across the breast and along the flanks seems more in line with a young male, since females, generally from what I can gather, tend to be the less streaked. The streaking along the flanks seems well-marked, so that doesn’t mesh well with the age as a young female.
  • the color of the underparts looks fine for hudsonius.

Primary Barring

Females can show less bars and a wider middle secondary bar compared to males. Primary bars (excluding the dark tip) of 15 banded female Northerns in Cape May had the following:
  •  P9-7 varied on both male and female. Males averaged 6 bars (lowest 5, highest 7) while females averaged 5.6 bars (lowest 5, highest 8).

The German bird shows 4 bars on these feathers and thus fits better with Hen Harrier

Vent Pattern

One feature I need to look at is do juv Hen harriers often (always??) show dark-centered under tail coverts while hudsonius tend to have uniformly rufous vents (hair-like shaft streaks in young males, but not really visible in the field). This bird appears, from the images, to show a hudsonius-like vent, but again I am not sure based on my knowledge, if Hen Harriers frequently show this. Northern’s, as far as I have seen, never show dark, redpoll-like markings on the undertail coverts which makes the German bird better for hudsonius – or a hybrid? -than perhaps a Hen.
I often find I change my mind when re-examining images of these kinds of birds (!) and also wonder about a hybrid  possibility and whether that can be ruled out, especially if the under tail coverts in juv. (HY) Pallid and Montagu’s  are unstreaked and Hen’s are streaked. I do not go to the hybrid theory quickly, but the head pattern and underpart streaking strike me as odd for that age class of a putative hudsonius and overall fit better with Hen.
It is an interesting bird, but in my opinion doesn’t fit neatly the criteria for a vagrant Northern Harrier . Further in-depth info on Northern Harriers can be found here:
Thanks Ralph for the shots!

Interesting “orange” harrier in Germany

January 21, 2014
Ralph Aumueller kindly sent me these images of an interesting harrier.
“When we found the bird on jan. 5th, our initial impression was of a pallid harrier, an impression what we had to reject immediately as we found the bird five-fingered, broad winged and so on. So it´s a Hen Harrier of some kind, but ruling out hudsonicus causes us quite a headache.
Almost all id-features neatly fit in the pattern awaited for a Northern Harrier (hudsonius), but we are much too inexperienced with that taxon. We are aware, however, that the underwing-pattern seems not to suggest a hudsonicus, with the barring on the outer primaries at the very lower (too low?) end of its range of variability. Additionally the middle secondary bar seems to be to wide. However we found in the literature that females tend to show a more cyaneus-like pattern in this respect. So we really reached the point to need  the help of an expert on that topic. May I therefore kindly ask you for  your opinion on the bird´s id? That would be fantastic!
Best wishes,
S0, in light of the recent British and Irish records of vagrant Northern Harrier (C.c hudsonius), this bird seems quite striking and scary. What do others think of this bird and what would you call this if you saw it. Be interested to hear people’s opinions on this before I post my comments I had sent to Ralph.

An interesting “Buff-bellied” pipit, Cheshire, UK, January 2014

January 14, 2014

American Buff-bellied Pipit (rubescens), Connecticut, USA, Jan 2008

A vagrant Buff-bellied Pipit (aka known as American Pipit or confusingly Water Pipit here in the US) is being seen at a coastal marsh in the north-western part of the UK. Buff-bellied Pipits, of the race japonicus, also occur in Asia and winter in the Middle East and this race and the Nearctic race rubescens show a great deal of variation and so separating these two in a vagrancy context may be difficult with some individuals.

While Buff-bellied Pipit, of the Nearctic race rubescens (American Buff-bellied Pipit) has occurred several times in Britain and Ireland, the Siberian race japonicus (Siberian Buff-bellied Pipit) has not, so it is worth noting the plumage features of any vagrant Buff-bellied Pipit to determine race.

Basically, the dumb-down cliff notes are that Siberian birds are:

  • pale-legged
  • rather pale below with a noticeable eyering
  • large, club-ended malar and streaked blackish below with rather tear-shaped spots/streaks.

American birds are:

  • darker-legged
  • rather plainer above,
  • being less streaked, more buff-below with rather more brownish, blurry streaking.

However, individual variation and wear and geographical variation across their ranges makes the “simple” criteria just mentioned somewhat useless in a vagrancy context, and identification is often easier if you are standing in Israel or Connecticut respectively!

The individual in Cheshire can be seen at (scroll down for the images if necessary) :

Initially, on a comment I posted on Martin Garner’s Birding Frontiers site I had thought the bird seemed fine for American Buff-bellied Pipit, but further photos seemed to show a bird with rather contrasting upper wingbar, rather large blobby malar and well-defined dark streaks on the underparts. I was cautious and wondered if the bird could be a Siberian Buff-bellied, but having no field experience of that race, I was in unchartered waters and wanted to add some caution to my initial support of the bird.

So, I dug up some pictures I had taken of a bird here in New Haven for comparison (see below) and also a link to Siberian Buff-bellied Pipit here:…f-bellied.html.

All three images, American Buff-bellied Pipit (rubescens), New Haven, CT, January 14th 2008.
Based on Pyle et al., 1987,  the pointed centres to the median coverts and the blurry, non-indented edges to the greater coverts makes this bird a first-winter (HY). The Cheshire bird is a first-winter by the same features.


3_rubescens_NewHaven_CT_Jan15th 1_rubescens_NewHaven_CT_Jan15th 2_rubescens_NewHaven_CT_Jan15thOverall a buff-brown bird, with non-contrasting wingbars and dull buff underparts. Underpart streaking is brown, not blackish and there is no pale contrasting eyering or large, dark, ‘blobby’ malar. Note the dark brown, not pale legs.

After reviewing images, and taking into consideration variability, with all things considered, the Cheshire bird is more likely American based on the overall plumage tones, plainer mantle and underpart color but it is certainly not straightforward. If the bird had been the rather white-below, heavily streaked Siberian birds, perhaps it would be easier, but since they vary so much, a vagrant may often be hard to assign to race.

American Buff-bellied’s have a distinctive, di-syllabic “pip-it”, “pip-it” calls that may help distinguish it from Siberian birds but I have no experience with that race.

A great educational bird that has generated some insightful discussions in the UK for those that want to read more on this bird:

The Ugly Show

January 1, 2014

After a flurry of Snowies hanging out at Long Beach over Christmas, despite consecutive days of doing the death march down Long Beach before sunrise, with fellow friends AJ Hand and Jim Zipp, we failed to score any photo opps.

CAM01153We did find one bird at Milford Point, or at least we thought we did did until we saw this sign on the Visitor Center window..

CAM01154When I returned home I found out one bird, that had been frequenting the harbor near my house, had showed up again briefly. But, when I arrived at the spot there was no owl to be found. Grabbing some breakfast before I went over to check the War Memorial at the bottom of my street, I got a post from John Oshlic  saying he had the bird actually perched on top of the war memorial. “Err, Nick, I’ll have those eggs and home fries to go…NOW!”

Two shakes of a lamb’s tail later and breaking the speed limit,  I had clocked the little beauty from the exit ramp as I got off the! Turns out, it was an ugly little bugger!!


Long Wharf, New Haven, CT…right by the house. I even got it on my “birds I’ve seen while running” list later on that day, sat out on the mud flats.Tick!



Breakfast! You can see the bird on top of the memorial!

The bird’s right eye seemed to be injured but it was hard to determine if the stain was old blood or from something else.

_MG_5708With birds starving and emaciated, it is no wonder some of these poor birds don’t seem to be doing well! Hope this guy is finding food!

"Ashy-face" - the bird at Milford looked as though it had been dragged through a hedge backwards and was later seen at Long Beach with an apparent broken/injured leg. :(

A Snowy Christmas 2013

December 24, 2013

_MG_4531 copyAn unprecedented number of Snowy Owls irrupted south this winter and made for some awesome opportunities to see these majestic creatures. Unfortunately since these flights are prompted by too many birds and not enough food, some were emaciated and starving and some were found dead as result. CT did well with several birds being rather photogenic. Thankfully many photographers remained respectable, though people trying to take photos of them with their smartphones continue to piss off everyone that understands that you can’t use your smartphone for bird photography unless the bird is embedded up your nostril. Really people…enough with the phone nonsense :)


Ace photographer and awesome dude AJ Hand and Alex getting to grips!

I used to think I could age and sex some Snowy Owls. While I think the heavily barred birds with boldly barred napes and minimal white “bibs” are females, and the lightly marked and almost white birds with broken tailbands are males, this isn’t always the case.

CAM01114 copy

Snowy Sunset

Birds with vermiculated inner greater coverts and primary tips may be first-years (HY) but I’m not sure older birds cannot show these in successive moults, so it really is hard to age and sex birds of unknown age in the field. Individuals often get lighter with age, stay the same, or get darker so there is a whole gamut of variation and overlap. Apparently according to Russian research, first borns in the nest are often paler than successive hatchlings which are darker! Also, some HY males (aged in the hand from banding / specimens) may overlap with adult females and may only be differentiated by size. Pyle mentions tail (?) feather shape (blunt and rounded vs bluntly pointed) as a means of ageing some birds, but this seems hardly useful in the field.


_MG_4889 copy


The only main way of ageing Snowy Owls to calendar year (after HY/SY) is perhaps during June-September when birds have an incomplete primary moult and it MAY be possible to differentiate between old and new primaries.

I have seen few birds in New England I would call “females. This fits the migration pattern which basically is that females, being larger and dominant, take territory further north and it is the males that are “pushed” out further south. It also makes sense, from a probability point of view, that many of these birds are likely HY birds.

So, it seems from conventional wisdom that while we may think a bird is a young bird, or most likely a female (if large and boldly barred) we are likely guessing a lot more than we think we are.

Not seeing the kumlieni for the hyperboreus- an id. put to rest

December 24, 2013

A first-year white-winged gull turned up last year at Long Beach, Stratford, CT It was well photographed and identified by various observers as a Glaucous Gull, then perhaps a hybrid. However, the pix show a bird that fits with kumlieni, albeit a very big one! I had mentioned my opinion at the time, but the bird continued to be discussed ad nauseum with some observers believing the bird to possibly be a hybrid, an opinion I was at odds with since there didn’t seem to be any hybrid characters. Although it returned this winter, it was still reported as a Glaucous Gull despite it having dark-washed primaries, a feature never shown by hyperboreus.

After a careful analysis of the photos, I concluded the pro-Glaucous features to be:

  • It was big!

The pro-kumlieni features to be:

  • It didn’t look like a Glaucous Gull!

Thankfully, it returned this winter in it’s second-winter plumage sporting the expected dusky webs to the outer primaries diagnostic of kumlieni. The bird’s large size was apparent, but not outside the range of kumlieni and I think many observers got too hung up on size and didn’t really assess the bird’s plumage features which, as shown are perfectly kumlieni.


Note the rather slim body and pointed wings and proportionately large eye. The solid, dusky tail and dusky outer webs to the outer primaries are diagnostic of kumlieni. The large mirror on P10 is visible in the enlarged version._MG_5424

2nd November, Fairfield County, CT

“Hey..check your email and check out Frank’s pix of that hummingbird ..” was the cryptic message Nick Bonomo sent me on a balmy Saturday afternoon. I was out with Alex and his friend on the beach and couldn’t make out crap on my phone, but Nick’s message implied that all might not be kosher with it.  I got back to the house and while talking on the phone, I pulled up Frank Mantlik’s photo’s of a “Ruby-throated Hummingbird” he had photographed a few days earlier at a private residence.

At that moment, as the images came up, I spat coffee all over my computer and realised why Nick had called me. It had outer primaries like a .!!@@ hockey stick. It was a young male BLACK-CHINNED HUMMMINGBIRD -1st state record!! Tripping overmyself to grab my gear and make phonecalls, it was apparent that several people had reached the same conclusion and were running around like headless chickens trying to find out if it was still there…problem..the bird had been there a week and it was 3 days prior that Frank had taken the images.

Frank called the homeowner to check and she said she hadn’t seen it in several days..arrgghhhh!!! But, as amazing as birding is, as she was talking to him on the phone, she saw the bird fly past her and feed on some salvia!!! TWITCH ON!!!

As soon as I arrived, the bird immediately flew in and performed down to feet..amazing. It came in several times, occasionally making flights up to hawk insects.Kudos to the homeowner for her hospitality and to Frank for sending out the could have gone so horribly wrong!

Finally, in  what has been a lacklustre fall, I dragged my ass into the field to look for birds. A previously reported Lark Sparrow had been seen at Hammonassett State Park, CT so since that was still a nemesis bird in the state, I thought I would spend some time there and give it a go. A great spot for birding, I figured it would be a great place to spend a nice few hours in the field on a glorious fall morning.

Arriving at the spot, I was told it had been seen earlier feeding with some sparrows. I patiently waited and saw nothing. After everyone had disappeared, it suddenly appeared, feeding in the leaf litter in front of me. Unfortunately it was flushed by a cyclist and so good views were brief.

Quite a dapper bird!

Quite a dapper bird!

After a while the bird flew out of some conifers, giving it’s “tink-tink” call and flew across the campground. I followed it and soon relocated it feeding out on the grass. I went all Seal Team Six on it and belly crawled close..unfortunately it remained in the shade for over half an hour. At this point, just as I was going to need a chiropractor for my neck,  it shuffled into some sunlight for a few seconds and I managed a few shots.

Definitely a crippler as sparrows go!

Difficult to age in late fall since juvs moult mostly on the summer grounds and thus lose most of their tell-tale streaky plumage. Since moult in this species is quite complex between geographic populations, it means that fall birds are generally not easy to age on plumage and best aged by the shape of their tail feathers. These looked pointed in other images which would make it a HY (first-year).

Planned It! Booked It! DID IT! California September 2013

October 17, 2013

Alvaro Jaramillo (centre) holds court on the “New Captain Pete” as we hit the continental shelf off of Half Moon Bay.

After a nice early breakfast courtesy of the Fairfield Inn, Phil Rusch, Nick Bonomo, Simon Harvey and myself found ourselves at dawn in Pillar Point Harbor, all prepped for a pelagic out of Half Moon Bay, San Mateo County run by an old acquaintance, Alvaro Jaramillo. I had done several trips out of Monterey in the late 80s and mid-90s with Debi Shearwater but had never ventured out of Half Moon Bay, conveniently only 35 minutes drive from SFO airport! This particular tour of duty involved a couple of Debi’s trips but while birding was OK, for seasoned veterans it was lacklustre. It seemed all the most interesting birds were being seen in Half Moon Bay this fall! So Saturday 14th September so us ready to rock and roll…and roll we was a bit bumpy on the way out!

It was great to see Alvaro and catch up a bit – we had first met when I was a research assistant at Long Point, Ontario in 1991 and he was living in the area. A great, incredibly knowledgeable guy, well-respected in the field community for his field skills he had recently left Fieldguides Inc. to go solo with his travel company Alvaro’s Adventures,  and part of his operation includes running several CA pelagic trips throughout the year that have produced a burgeoning list of seabirds that have included such vagrants as Hawaiian Petrel, Short-tailed Albatross, White-chinned Petrel, Great-winged Petrel and MANY Laysan Albatrosses.

One of the first notable differences from the other pelagics, was complimentary coffee and croissants on the boat as we waited to get underway..nice touch! Alvaro ran a nice trip, engaged with all the participants and gave an educational running commentary about the birds and marine life of Half Moon Bay. A nice trip with a great selection of birds, and I would thoroughly recommend anyone taking a trip out west to take advantage of the convenience of Half Moon Bay trips with Alvaro.

Several dapper, pterodroma-patterned Buller’s Shearwaters were seen in good numbers


Great looks at this Pomarine Jaeger with “spooners”. Being a rather northerly wintering jaeger, Pomarines, unlike Parasitic and Long-tailed, begin primary moult in the early fall – this bird is moulting its inner primaries. Dark underwings lacking any barred feathers suggest it is an adult and the breast band and barred flanks suggest it is a female.

Parasitic Jaeger, Cape May Point, 29th Sept 2013

October 10, 2013

While spending time in Cape May with my son, I stopped at the Magnasite Plant in the early evening of the 28th September 2013 to look for Northern Harriers and Merlins that often hunt at dusk in this area. I bumped into Jonathan Wasse and Peter Lansdown, visiting from the UK, and as we were chatting, Jonathan noticed a gull soaring over land and said “That Herring Gull is doing a good job imitating a skua (jaeger)”. Even distorted by the windshield, it didn’t look like a gull and immediately looked interesting and jaeger-like. Jumping out of the car, I snapped a few flight shots as the bird flew over us and drifted away towards Lily Lake. Clearly a juvenile Parasitic from the views we had and quite strange to see it circling over land.

That was the end of that…or so I thought. The following day, I arrived at the hawk watch at Cape May Point, when I was greeted with shouts of “Jaeger on the pond!” Indeed there was! A juvenile jaeger was sitting on the pond close to the platform. From the looks of it, it was the same bird we saw the evening before..and perhaps the same bird that had been seen briefly at the same spot the day before by the CMBO-appointed hawkwatcher Tom Reed.

Juvenile Parasitic Jaeger, Cape May Point, NJ, 9/29/2013 (Julian Hough)

Juvenile Parasitic Jaeger, Cape May Point, NJ, 9/29/2013 (Julian Hough)

The following features were typically pro-Parasitic:
  • Longish-spiky bill , not really stout with a dark-tip that appeared to be a 1/3 or so of the bill
  • Disproportionately small head, with streaky cheeks and a short, steep forehead. The slightly raised crown giving a more triangular-shaped head rather than a domed, rounded head
  • Overall warm cinnamon/nutmeg tones to the plumage, especially the pale upper part feathers and primary tips
  •  Prominent, chevron-shaped primary tips, tinged pale buff-brown, not white.
Identification of juvenile jaegers can be problematical, but the good views of this bird made for an easy identification as an intermediate-type juv. Darker, juvenile Parasitics can be difficult to separate from some dark juvenile Long-taileds. The pale-fringes to the primaries can be shown by both Parasitic and Long-tailed, so they are not diagnostic, but coupled with other features may be used as a supporting character. On some images, the pale fringes to the primaries in Long-tailed tend to be narrower and paler, while those on typical Parasitics, like the Cape May individual, are well-defined and chevron-like.
Overall a great bird to see and photograph!
