Scope Watch

Birding situations often arise where we need greater magnification than binoculars can provide. I'm not one for humping a telescope and tripod around. I like to travel light, and very often my camera on a shoulder is second only to a pair of bins around my neck. But I always make sure there’s a telescope in the car for those occasions when birds are a long way off and maybe one or two require special attention and a more detailed appraisal. 

A telescope can be an expensive piece of kit but is probably essential for someone looking to expand their birding into new territory. Here’s a round-up of some of the best scopes on offer at the moment, so if you’re in the market for greater magnification, check them out. 

I have not included prices as these vary to some extent. I believe that the ones featured below are available on both sides of the Atlantic, Europe and other continents. Yes, birding is a global phenomenon as shown by the “hits” on Another Bird Blog from the World over. 

Here are those telescopes. 

Vortex Razor HD 27-60×85

Vortex Razor HD 27-60x85 

I use inexpensive Vortex bins. I rather like the brand because their robust build with sharp optics take a hammering from almost daily use in all sorts of weather. 

The Razor HD 27-60×85 scope is engineered with an oversized objective, superior glass, and specialized coatings. It gives clear and bright images at all magnifications and lighting conditions. It also minimizes light loss and maximizes image brightness with Vortex’s XRPlus anti-reflective coatings. The Porro prisms have highly dielectric coatings designed to improve brightness, clarity, and colour accuracy. 

Kowa TSN-553 15-45×55 

Kowa TSN 553 14-45 x 55 

The Kowa TSN-553 15-45×55 uses low-dispersion PROMINAR fluoride glass that reduces chromatic aberrations that when paired with the multi-coated optics and two-speed focusing mechanism produce bright and clear images. The impressive zoom range allows the user to take in a wide field of view for general viewing purposes and the ability to draw subjects in close for more detailed observations. 

Swarovski ATS-65 HD 20-60×65 

Swarovski ATS-65 HD 20-60 x 65 

The ATS-65 HD Spotting Scope with eyepiece is a rugged yet refined scope from Swarovski. It is compact, relatively lightweight, and particularly well-suited for birders who like to carry a scope at all times. Swarovski’s ATS series combines the high image quality and world-class workmanship consumers can expect from this renowned company. 

ZEISS Victory Harpia 85 

Zeiss Victory Harpia 85 or 95

This is the rather expensive flagship of the Zeiss range. The extra-low dispersion fluoride glass of the ZEISS Victory Harpia 85 or 95 Spotting Scope ensures crisp and sharp views. 

The Harpia is somewhat unique. The wide-angle zoom mechanism has been placed in the objective end of the scope near the focusing wheel, not in the eyepiece, which allows greater flexibility in the way the image is presented.  The makers say that it is easy to clean off oils, spots, dust, and dirt without residue due to the LotuTec coating on the exterior lens. Sounds like the one for me, but I need to save up for one or raid the grandkids' piggy banks.

Leica APO-Televid 82 25-50 x 82

Leica APO Televid 82 25-50 x 82

Lightweight, easy-to-manage, and offering top optical performance, the APO-Televid 82 delivers brilliant views of nature that are rich in detail and contrast. In addition to conventional viewing, there is a special camera adapter that allows it to convert into a high-powered telephoto lens. 

The above is just a selection of the telescopes you can find on the Internet. Very often there is a You Tube video with a spoken review and detailed analysis of the product.

Try a DuckDuckGo search for “birding telescope”. You will get something like 240,00 results! Good Luck.

The Friday Feeling

Thinking that Friday morning might be OK for birding wasn't a great decision. The broken rainbow that fell from black clouds above made a pretty good pointer to the never ending showers that followed. It was windy too, much more than the Granada forecast and the whole morning felt like September had well and truly arrived. 

A Cockerham rainbow 

It was two weeks since I last visited Conder Green (25th August) so I headed there first. I'm not sure where the wagtails had roosted overnight but the first stop for many of them was Conder Pool where I counted a remarkable 80+ Pied Wagtails and 2 Grey Wagtails along the far bank. The wagtails were so far away that I'm pretty sure more were hidden out of sight over the bank and behind the pool. 

This last week saw a push of Swallows headed south and it was noticeable today how few were around with 70+ feeding over and around the early morning hedgerow the best count by far. Otherwise there were just twos and threes along the lanes towards Cockersands where last broods are still about the farms buildings. 

Swallow 

The grassy margins of Conder held large numbers of Lapwings, so numerous and so mobile that a count is of 450+ is but an estimate. Once or twice the loose flock erupted into a cloud of flight as if all of those present received the same message of danger at precisely the same moment. Birders call the spectacle a “dread”. The more scientific term for the phenomenon is “Swarm Intelligence” or SI. 

“Although there is no centralized control structure dictating how individual agents should behave, local, and to a certain degree random, interactions between such agents lead to the emergence of "intelligent" global behaviour, unknown to the individual agents. Examples in natural systems of Swarm Intelligence include ant colonies, bird flocking, animal herding, bacterial growth, fish schooling and microbial intelligence.” 

Other waders and wildfowl today – 32 Redshank, 5 Greenshank, 3 Snipe, 2 Black-tailed Godwit, 2 Common Sandpiper, 14 Teal, 3 Little Egret. 

Greenshank 

Very evident today was the number of Starlings. This is the time of year when we have an influx of Continental Starlings that spend the winter here in the UK rather than colder parts of Europe. Twice I saw newly arrived Starling flocks pursued by raptors – firstly by a Sparrowhawk and then later by a Merlin. Neither raptor caught their breakfast. 

Sparrowhawk 

I stopped off at Gulf Lane where I saw the earlier mentioned Merlin. The Merlin had scattered a field full of Lapwings, Starlings and Curlews which is no mean feat for a bird hardly bigger than a Mistle Thrush. The Merlin flew towards the junction and left a dread of waders in its wake as it inspected the field of set-aside where I’d just counted 35 Goldfinches and 20 Linnets. 

We have cut a ride for when finch numbers build.  We think that the good summer, a glut of natural food together with a prolonged breeding season may have delayed the arrival here of  both Linnets and Goldfinches. But when they arrive in numbers we are ready with an already cut catching area to build on the 400+ Linnets ringed during the last two winters. 

By now it was raining again, more heavy showers, grey skies and quite windy. I called it a day and headed home to catch up with news, birds and the “real” world. 

We seem to have left summer behind but my pal David in Waterloo, Ontario, Canada tells me it was 35 degrees there on Wednesday. You can read about his weather, birds and bird ringing, together with his liking for coffee and cake on his blog Travels With Birds.

Purple Patch

I was unavailable for Tuesday’s ringing session when Andy ringed another 35 birds at Oakenclough. He caught the first Siskins and Lesser Redpolls of the autumn and another couple of Tree Pipits but then excelled by catching an adult Spotted Flycatcher, the first full-grown “spot-fly” for a number of years. 

Not to be outdone I met up with Andy for another 0630 start on Wednesday. Oakenclough’s recent purple patch continued with 42 more captures of 12 species. There was an exciting morning of birding too, topped off by an adult Hobby about 11 am. 

We caught steadily from the off as finches provided the numbers while “others” provided the “star” birds: 14 Goldfinch, 9 Chaffinch, 4 Great Tit, 3 Meadow Pipit, 2 Blackcap, 2 Willow Warbler, 2 Goldcrest, 1 Chiffchaff, 1 Siskin, 1 Lesser Redpoll, 1 Tree Pipit, 1 Blue Tit, 1 Coal Tit. 

Both of today’s Blackcaps, a male and a female were birds of the year (juvenile) with the female showing faint fault bars on the tail. Fault bars are pale bands sometimes seen on wing and tail feathers and which are probably due to reduced metabolism with less melanin deposition during the growth of feather, typically during days when food is scarce due to natural causes or poor weather. We have seen few fault bars on young birds’ tails this year, almost certainly a consequence of the best year ever of UK weather as a whole and the best since 2006 in the North West. 

Blackcap 

 Blackcap- juvenile/first year female 

Today’s single juvenile Tree Pipit had a tiny mite attached to its face at the bottom of the right eye. We occasionally find such things around the eye and head of a bird but without specialist knowledge we can do little if anything to help. However, it is said that such ticks drop off when the ticks are finished feeding without any long term effect on the bird. 

Tree Pipit

Meadow Pipit 

I hope everyone spotted the difference between Meadow Pipit and Tree Pipit? 

Chiffchaffs have been strangely absent this summer and autumn, today’s recently moulted adult the first since 26th March. 

Chiffchaff 

In recent years we are finding a number of juvenile Goldfinches in full primary moult (replacing all of their primary feathers) in late/summer early autumn. These are juveniles from the earliest broods of April/May and June whose plumage is well worn by late summer. In the picture below the outer feathers are the browner and worn ones; the darker, blacker ones and the short, still emerging feather are the new “adult type” feather. However, the bird is still classed as a first year/juvenile until 1st January 2019 when of course it becomes a second year.

It’s good to welcome back Siskins and Lesser Redpolls even though we caught just one of each - both adult females.

Tail feathers

The birding was pretty spectacular this morning, even with the limited time between rounds. There was an early arrival of 150+ Swallows which arrived so soon after dawn that we thought to be from a local roost. As the morning progressed their numbers increased at the same time as a large influx of House Martins and a handful of Sand Martins. Our estimate of the numbers involved in both visible migration and those lingering while feeding was 375 Swallow, 260 House Martin and 10 Sand Martin. 

With so many hirundines about, we speculated about the possibility of a Hobby. About 11 am Bryan cottoned on to a raptor that arrived from the west and shot quickly through where the Swallows and House Martins were feeding. We had less than a minute as the Hobby circled and then flew directly over our heads where we were able to identify it as an adult rather than a bird of the year. 

Hobby - Falco subbuteo 

Other birds – 8 Grey Wagtail, 6 Pied Wagtail, 7 Buzzard, 2 Sparrowhawk, 2 Great-spotted Woodpecker, 1 Spotted Flycatcher, 1 Nuthatch. 

No Two Days Alike

Most bird ringers will agree that going to the same place on consecutive days may not be a good idea. That’s probably true for sites where the majority of birds are likely to be from a small local area but does not apply where a site attracts migratory birds, ones that are likely to be different individuals each day. And the theory definitely doesn't hold water in migrant hot-spots like coastal bird observatories where both ringing and observations on consecutive days is an absolute must to record day to day variations. 

I guess our site up at Oakenclough is a mixture of the above. For sure there are local birds but located as it is on the edge of the Pennines and with a clear view down to the coast just 12 miles away, there can be a large element of migration at certain times of the year. 

Andy and I had already been twice this week and clocked up almost 80 new birds, the latest on Thursday when we caught 52 of 10 species. So we had no qualms about heading up there again this morning and arranged our meet-up for 0630. 

Thursday was a pretty busy day but this morning produced a downturn in both numbers caught and species observed. Birds ringed 23. We processed 7 Goldfinch, 3 Chaffinch, 3 Long-tailed Tit, 3 Coal Tit, 2 Tree Pipit and singles each of Blackcap, Robin, Great Tit, Goldcrest and Wren. 

Today saw our ninth Tree Pipit of the week. All nine have been first year (born 2018) birds.

Tree Pipit 

After three new Coal Tits yesterday, two more today tells us that the species’ migration is probably under way. 

Coal Tit

Long-tailed Tits are definitely local birds. But we have not seen any large flocks of “lotties” just yet, flights that can number up to twenty, thirty or more individuals following good breeding success and mild winters. 

Long-tailed Tit 

Although we caught just the one Goldcrest today, there is little doubt that their autumnal migration is now on-going. 

Goldcrest 

We didn't record Willow Warbler today; our only warbler sighting consisted of the single Blackcap we caught, a first year male. Although Blackcaps breed close to this ringing site we are pretty sure that the three first years birds caught this week have been migrants. 

Blackcap 

This morning gave a good display of Chaffinch visible migration as small parties of between 2 and 20 individuals arrived from North and North West, flying overhead calling. From the total of approximately 80 observed, A small number stopped off and accounted for the three caught. 

Chaffinch 

About the only other visible migrant today was Swallow. Like the Chaffinches that moved in a similar time frame our Swallow sightings consisted of small parties of between 5 and 15 Swallows all heading south, either directly through or over the ringing site. 

Otherwise: 1 Buzzard, 1 Kestrel, 1 Spotted Flycatcher, 10 Pied Wagtail.

Back For More

The forecast of little cloud and a 4 mph wind for Thursday looked so stable that we actually confirmed our arrangement for Oakenclough on Wednesday afternoon. This is a most unusual occurrence that more often than not involves a detailed discussion around whether a ringing session is even possible in our normally unsettled weather. 

I met Andy and Bryan for the 0630 start to a perfect morning of zero wind with just a little cloud together with a hint of sun peeking around the corner. 

Birds were on the move from the off and the morning proved productive for both ringing and birding. Goldfinches dominated the catch but we also bagged a few warblers and more Tree Pipits to add to those of Tuesday. 

Today’s catch comprised 52 birds of 10 species; in numerical order - 20 Goldfinch, 8 Chaffinch, 6 Goldcrest, 5 Willow Warbler, 4 Tree Pipit, 3 Coal Tit, 2 Blackcap, 2 Robin, 1 Great Tit, 1 Greenfinch. 

The twenty Goldfinches included an adult bearing a ring immediately recognisable as not our own due the unfamiliar series of letters and numbers – S524171. Otherwise the remaining Goldfinches proved to be first years/juveniles. Almost without us trying very hard it’s looking like Goldfinch will become the most ringed bird of 2018 due simply to its abundance in town and country. 

Goldfinch 

All four Tree Pipits proved to be first years/juveniles. All seven we have caught this week have been first year/juveniles. This is not surprising given that by the end of the summer birds of the year will outnumber adults in the ratio of approximately 5/1 and also that adults are thought to migrate earlier than juveniles. The recovery rate for ringed Tree Pipits is actually quite low, despite ”acute persecution” in Southern France and Northern Spain (BWP).

Five Willow Warblers gave opportunities to directly compare adults (born before 2018) with first years (born 2018).

The two Blackcaps were first year birds, one female and one male. 

Blackcap 

We discussed how we’d not caught a Coal Tit for months and then, lo and behold, three turned up in quick succession, together with a single adult male Great Tit. 

Great Tit 

Not so with Blue Tits as they remain hard to come by up here – rather a strange thing to say about the most ringed bird on the BTO’s books. Our own observations and casual chatter elsewhere suggest Blue Tits may be the next to suffer from a drop in numbers. 

From as early as 0700 there was a noticeable movement of Swallows overhead which tailed off about 0900 by which time we had counted 80+. As the morning warmed more Swallows arrived from the North West together with smaller numbers of House Martins as both species aerial fed in numbers approached a combined 250/300 or more. 

Finches were also on the move as shown by our catch of both Goldfinches and Chaffinches with small parties of both throughout the morning. Not so with Lesser Redpoll, this has yet to appear as an autumn migrant up here. 

A number of Pied Wagtails appeared in late morning with 15/20 feeding nearby and a couple or more noted flying over and due south. Other birds noted in addition to those caught – 15 Willow Warbler, 2 Sparrowhawk, 2 Spotted Flycatcher, 2 Great-spotted Woodpecker, 1 Song Thrush, 1 Peregrine, 1 Treecreeper. 

Great-spotted Woodpecker 

The Spotted Flycatchers were along the nearby woodland edge of someone’s garden. These were the first I’d seen since May in Menorca where Spot Flys are ten-a-penny, unlike the UK where the species is another one in decline. 

Spotted Flycatcher 

The flycatchers were a good way to end an interesting and rewarding morning. And with the same forecast for Friday, who knows? We may be back for more.

Gamekeeper Shoots Short-eared Owls

There's nothing much to add to the video below. Watch and see if your blood boils.

 

For this outrageous and despicable crime the derisory “punishment” handed out by the court is equally outrageous. The perpetrator Tim Cowin was fined £400 for killing each owl and £200 for possessing a calling device, which was forfeited by the court. He was ordered to pay £170 costs and a £40 victim surcharge. A total of £1,210.

This kind of cruelty and disregard for our wildlife will continue until proper sentences are imposed and landowners become liable for crimes committed on their land.

Back soon with more pleasing news.

Slowly Does It

This ringing lark gets more difficult to predict. After the rain and wind of Sunday and Monday we felt sure that a fine start to Tuesday might produce an influx of birds to our site at Oakenclough. I met up with Andy at 0630 and then we waited, and waited. 

It was a good thing that the feeders were well topped up because that is where we realised the majority of our 20 birds, mostly finches: 14 Goldfinch, 3 Chaffinch, 1 Blackcap, 1 Willow Warbler and 1 Goldcrest. 

Of the 14 Goldfinch, 11 were birds of the year in varying stages of post-juvenile moult. An adult female had a clear and well-defined brood patch suggestive of current or very recent breeding this late in August. Such determined productivity and willingness to adopt the suburban garden defines the outstanding success of this now abundant species. 

Goldfinch 

In the field someone might easily label the below Blackcap as an adult male because of the black cap. Closer scrutiny showed a juvenile/first year tail but also, the tell-tale remnants of a juvenile brown cap. By late August juvenile male Blackcaps show hardly if any brown in their black caps.

Ageing autumn Willow Warblers in the field is very hard, some might say impossible with any degree of certainty given the often brief views of a tiny warbler flitting through the greenery. 

The process is much easier in the hand when we employ an understanding of the moult strategy of Willow Warblers to separate the two age classes. Adult Willow Warblers go through a complete autumn moult while juveniles undertake a partial moult, so that by late summer/early August individual birds of different ages can initially appear identical. 

The tails of adults are typically broad, rounded with little or no abrasion; juvenile tails are usually narrower, more pointed and usually look more worn that the equivalent adult tail. In general but not absolutely, adults have whiter bellies than first year birds. 

Willow Warbler 

There seemed to be little visible migration this morning with just tiny groups of Goldfinch and Chaffinch making their way overhead. We saw 10-20 Swallows heading south and a probable local Sparrowhawk. 

We followed up a sighting of a few days ago – five or six Little Ringed Plovers on the margins of the nearby reservoir where the water level remains at summery lows. Yes indeed, 5 Little Ringed Plover. Thanks Peter. 

Little Ringed Plover 

Looks like a day off tomorrow. But back on Thursday with Another Bird Blog.
