Boxed In

We’re not so much boxed in. More like locked in and fastened down until the experts say it’s safe to go outdoors. I doubt we’ll get to check nest boxes in 2020.

Here’s a previous visit to nest boxes at Oakenclough at the foot of the Pennine Hills back in the early summer of 31 May 2015. 


As promised, here is an update on a visit to Oakenclough on Saturday to check with Andy the progress of his nest boxes. 

The target bird for the nest box project is Pied Flycatcher (Ficedula hypoleuca), a small passerine bird of the Old World flycatcher family and part of a group of insectivorous songbirds which feed by darting after insects. 

Pied Flycatcher

This flycatcher winters in tropical Africa, spending the summer in the northern hemisphere but as far south as the Iberian Peninsula where it is quite common. 

Pied Flycatcher  

Pied Flycatchers breed in upland broad-leaved woodland. This means that in Britain they are limited due to geography mainly to the North and West where they prefer mature oak woodland with natural tree holes, i.e. dead trees, or dead limbs on healthy trees. 

The species also takes readily to nest boxes with high horizontal visibility, in woodland where there is a low abundance of shrub and understorey, but a high proportion of moss and grass for their nests. 

Andy - checking a box 

As is usually the case,  a good number of the boxes checked were occupied by Great Tit or Blue Tit with the adults still brooding tiny youngsters or sitting on clutches as low as 4 eggs or as high as 14 eggs. Given that the weather in the month of May has been mostly poor, the progress so far has been better than expected. 

Pied Flycatcher 

We found one box contained Nuthatches and ringed 6 youngsters. Four boxes were occupied by Pied Flycatchers where we found females sitting on either 6 or 7 eggs and where by a week or so the youngsters will be large enough to be ringed. 

The eggs of the Pied Flycatcher are about 18 mm by 13 mm in size, pale blue, smooth and glossy. The female builds the nest of leaves, grass, moss and lichens, and then lines the cup with hair and wool. The duties of incubating the eggs are performed by the female with the newly-hatched young fed by both adults.

The female builds the nest of leaves, grass, moss and lichens, and then lines the cup with hair and wool. The duties of incubating the eggs are performed by the female with the newly-hatched young fed by both adults. 

The Pied Flycatcher is a well-studied species, partly because of its willingness to use nest boxes provided by bird watchers and bird ringers. 

Detailed study has found that Pied Flycatchers practice polygyny, usually bigamy, with the male travelling large distances to acquire a second mate. The male will mate with the secondary female and then return to the primary female in order to help with aspects of child rearing, such as feeding. There are a number of theories around how this apparently poor system benefits the species, but no one knows for sure except that in practice it does work. 

In 2005 the European population of Pied Flycatcher was estimated at up to 12 million pairs, helped in part by the provision of nest boxes in parts of the species’ range. We checked our ringing site for Willow Warbler nests and found at one nest a brood of tiny youngsters, at another nest a female sat on 6 eggs. Dotted around the site a good number of males are in steady song with little sign of their mates, suggesting that most are still at the stage of incubating eggs. Willow Warblers are now a little late this year, no doubt as a result of the poor Spring weather to date.

Fast Forward to 2020. People aren’t perfect. Some slow to adjust while others appear to be in denial that coronavirus is something to be taken seriously.  The vast majority are trying to stick to the rules as best they can while doing the necessary to put food on the table and stay sane.

Back soon with Another Bird Blog.

Until then, linking with Eileen's Blogging.

I can see that this virus is going to mess up your plans this year Phil, unlike me Im trying to get the wildlife to come to me. with a little bit of success so far. Stay clean, Mike.

After we were required to remove our birdhouses from the shore area two years ago I only have one left. It's for tree swallows and they use it every year. Hope they are doing well in my absence during this isolation period in the city. - Margy

It's not easy but we have to take this virus seriously …

Nice to see your photographs.
My good wishes to you and your family.

All the best Jan

You asked why we had to remove the birdhouses from shore. Our float cabin in on a B.C. water lease. It does not include shore structures. We had a legacy small shed on shore that they required us to remove 18 years into our 20 year lease. The birdhouses were mounted on the shed. The only remaining one is on a pole in my floating garden which is inside our lease boundary. - Margy

Phil - what more can we say about the pandemic? Your term 'boxed in' is an apt description. But very glad to have the distraction of your bird photos! I am still waiting for most of our spring birds to arrive!

Love that little rascal!
(In Finland it usually steals the Blue Tits' nests...)

Hello again Phil …
Thought you may like to see this!


All the best Jan

PS Thanks for the recent Darwin's Award link you gave on the low carb diabetic blog

Hello Phil.
What a coincidence - I was just looking at old Flycatchers pictures, too. Take care.

Elkes Lebensglück said...

an interesting contribution with such beautiful photos of the young birds!
Everywhere it is that one is limited and yet glad that I can be in nature without people again and again!
Stay healthy
Greetings Elke

Hello, Phil,

It is hard staying safe inside when all I want to do is go out.. We can go for a walk, some parks and trails are open. We just have to keep a safe distance. Your Pied Flycatcher is a beautiful bird, love the cute baby. Great post and photos. Thank you for linking up and sharing your post. Take care, stay safe! Enjoy your day, wishing you a happy weekend.

Why this was just like watching a PBS special on tv!! You two gentlemen do so much for the education of bird life. I so admire what you do. I adore the chick!

(I'm here visiting from Saturday Critters today!)

Glad you have memories and photos to keep you busy.

Wonderful snaps, Phil. I love the bird in the banner.
God Speed mate!
