Teifi Redwings and Firecrest

Rather a chilly start to ringing on the Teifi marsh but a good early winter session with 33 birds caught.
The highlight was a juvenile Firecrest, the 5th ringed on the reserve since 2009.

Other species ringed included 10 Redwing, 3 Goldcrests, 1 Coal Tit (unusual for the reserve) and a Woodpigeon. Also a very fat male Blackcap with a fat score of 5 weighing 21.8g.

For anyone attending the Pembrokeshire Bird Conference tomorrow - we have a Teifi Ringing Group display so come and say hello and find out more about our activities.

Coral Snake....Night life on the jungle floor

The view with a light beam....

The Cano Palma forest...... where we have 16 net rides.
The following is a night-time wander with Joan and David, herpetologists from Spain, visiting the station and joining us for banding,... birds will follow !

The day-time beauty of the forest hides .....

  Tarantula sp. were not hard to find.....thankfully they are impossible to find during the day !

Different frogs appear at night too...this species of tree-frog, an unusually dull looking, but smiling one.

This Norops lizard - one of 150 species of Norops lizards. He must think he is rather smart when he inflates his throat ?  Below features a species of web-casting spider, it builds a mobile web....and uses it like a racket to catch prey...

A close up....amazing lines as ever with a spider....

Joan and David  wanted snakes..!!..This one from the night before...a Coral Snake.

 A very colourful example of this deadly snake....and our trio of night time trackers take a closer look in  daylight.

(left-right) Joan, David, and Manuel the expert local tracker based at Cano Palma Research Station.

This a Tree Boa, not the crushing power of the Boa Constrictors we found recently...but these are around too.
Just a couple of the c170 species of snake found in Costa Rica, and a tiny sample of life in the Caribbean Lowland Rainforest.

In the morning and banding at Cano. Interesting as ever, with Western Slaty Antshrike, Chestnut-backed Antbird, and this, Chequer-throated Antwren, one of two caught.

A young juvenile, seems likely to have fledged outside the known breeding period..?

Today we finally caught our first Gray Catbird of the season !!

Hopefully not our last migrant species of the trip.....

Teifi news - Siskins and Redpolls..

A good mix of species were caught during a short session on the Teifi Marsh on Saturday including a Chiffchaff, Blackcap, Songthrushes, Goldcrests and Blackbirds. This is the latest date that a Blackcap has been caught on the reserve although overwintering birds have been ringed in gardens before.

The group have only ever caught 4 Lesser Redpolls so to have ringed over 20 this month is noteworthy. We also retrapped a male that was ringed on the reserve last year - here he is when ringed last October.

Some news from the BTO of recoveries of some of our birds.
Out of the 235 Siskins ringed in my garden earlier this year there have been two recoveries so far.

One Siskin ringed last March was caught at Lake Vyrnwy in Powys in July and was seen several times on the feeders so possibly bred there. Another Siskin ringed in February was caught 45 days and 366km later in April in Stocksfield, Northumberland.

Also news of the original ringing details of 2 controls caught on the Teifi Marsh. A Sedge Warbler caught on 16th May 2013 was ringed in Tour aux Moutons, Loire Atlantique, France on 23rd August last year on its first migration south.
And this Sedge Warbler...

that we caught on 26th June 2013 was ringed on 10th August 2012 at La Claire Mere, Guernsey.

Weather for the week looks like ringing will be limited so a catch up of some more Costa Rica birds in the next blog.

Boa before Black-throated Trogon

530am - Another Boa found by a Alfredo and Alberto, our night-time naturalist security guards. We were just about to catch our boat to Tortuga Lodge, but this six foot Boa delayed us.

The legs were going to the beach -  surveying Green Turtle nests......!
With numbers of migrants well down now, our attention is back to the study of resident birds. We start with this wing moult....

Yes, the wing belongs to a wren....a Stripe-breasted Wren. Not a familiar moult pattern, but an example of the symmetrical and sometimes asymmetrical moult patterns that resident birds have here.

The star bird of the day appeared to have replaced one central tail feather. Presumably through accidental loss ?

Does the green on the outer edge of this newly replaced central tail feather indicate this is a young male..?

This is the bird, a juvenile Black-throated Trogon ......the bird of our day.
A wet morning with heavy tropical downpours, and since our last visit three net rides lost to fallen trees.
This is net ride 13. When a tree falls here, others come down too, creating a great hole in the canopy through which sunlight or rain pours down...often at the same time !

 

The recent rains have filled the forest floor with lizards and poisonous Strawberry Poison-dart Frogs....        

                                           

Hundreds of frogs and lizards leaping about as the water rose. If the rains continue, and net rides continue to disappear, this maybe my last visit to Tortuga Lodge.....

..........Until next year.......

Back to Reality

Just to show that we who were left to hold the fort for the last two months haven't been entirely idle, here are a few of the 17 Lesser Redpolls that were ringed during our last session on the Teifi Reserve a few days ago.

Ageing and sexing Redpolls isn't always easy by any means, so this was a very good opportunity to refresh our skills. The two above were an adult female and an unsexed '3', i.e. a bird fledged this year; with their colouration enriched by the light of the rising sun.

No one could be in any doubt about this adult male though, resplendent in his freshly moulted plumage - and by far the brightest of the bunch.

Costa Rica Highland birds

Back to the world of internet and a catch up of what we have been up to in the last  2 weeks at Madre Selva in the Talamanca Mountains of Costa Rica. Our base at 2,500 metres has 3 ringing sites each slightly different in habitat. Compared to our time on the Caribbean coast we caught few migrants and those that we did were mainly species that spend the winter in the lightly forested farmland

like Wilson's Warblers

and Black-throated Green Warblers.

One unexpected migrant to find in a net though was this Broad-winged Hawk

Among the  resident birds that we saw but didn't catch on our last visit was this Paltry Tyrannulet shown in the Lakeside habitat where it is found.

Collared Redstarts are frequently seen around the lake too

Along with Black-capped Flycatchers

Olive-striped Flycatchers

and Flame-throated Warblers.

Some birds that we caught that were more often heard than seen in the forest  included Black-faced Solitaire with a far-carrying flutelike song

Sooty-capped Bush-Tanager

Common Bush-Tanager

Large-footed Finch, both juvenile

 and adult,

Ruddy Treerunner

Chestnut-capped Brush-Finch

Spotted Barbtail

 the aptly named Yellow-thighed Finch,

and Spot-crowned Woodcreeper

The species we caught most of at Madre Selva was Ruddy-capped Nightingale Thrush

Some more Highland specialities in the next blog.....

Before the highlights of the Costa Rican Highlands.......

Wendy, just home from catching 110 species in Costa Rica will post some photos and describe this year's adventure into the last part of our trip - the Highlands.

Her final bird in the hand though, was this juvenile Prevost's Ground Sparrow, a great little find at InBio in San Jose, our final ringing site together.
Meanwhile Ivan and I have just arrived back in Tortuguero - to the expected rain and swollen canals of the Caribbean lowland forests.

Ivan, a ringer and researcher from Spain joined us about a month ago and will ring with me until  I leave on 10th December. Here Wendy and Ivan sharing the cooking on the fine wood-burning stove at our recent Highland base.

Highland highlights next..........
