16 February

Since the 16 February the nesting started. The weather is cold: 0° C in the morning. The first green moss strands were brought. The female tit which prepares the nest  alone. The male, enters the nest after a small dance, tail  raised  and wings lowered, but does not seem to be tolerated any more in the nest. He comes out  as quickly as he is went in, as if he had firmly been requested to leave at once. Then he encourages her, and sings perched in his birch, beside the nest.  Also, now and then, he brings her some offerings. 

Bouchée de mousseMousseSometimes, the billfuls of moss, too large, have difficulties to pass trough the door and remain partly hung at the entry of the nest. After a first good layer of moss, a layer of straw and dry grass completes the nest.


end of March

Finally, in the last week of March she adds, cotton, filaments and feathers, for a quite soft layer. Plumes


All the materials are tested. Our  hairy candle cactus was  mowed and is now in the nest.


At the end of March, weather is very cold. Frost in the nights. In the afternoons temperature attains only 2-3° C.

Works are in progress in all the nests. A “moinette” mows our asparagus with application. And sets out again with large mouthfuls of leaflets, a little prickly perhaps, but each to his own!

 1 April

Since the 1st April, she comes to sleep in the nest every evening, at dusk.lui le matin

And she now will do so every evening.

He awaits her very early in the morning, it is still night at 7h when he arrives and he will sing on the birch until she decides to rise. Sometimes she delays, sleeps on, he gets impatient! Probably all the neighbors are awakened before her by his teet, teet, teeeeet.
Le matin

At last, she comes!

Le matin

Ailes baissées

He comes and perch close to her, with the cap lifted, the wings shaking, half-opened and lowered, the tail lifted.

During of the day, she continues to adapt the nest to her taste and not only the interior.

She would like to enlarge the entry hole!

What does she want? 

Her blue cap is ruffled at the entry hole.



Before taking a small rest in the sun.

The nest seems almost finished. She still adds there some beautiful feathers, she  does not resist.

10 April: Today she went to bed much earlier than the other days, while there was still light.

11 April

This morning, one egg!     

Premier oeuf

It is always quite cold during the morning, 5° and 10°C in the afternoon.
She now will lay an egg the every day. She covers and hides her eggs in the morning, and the both tits spend the day outside. She passes from time to time in the course of the day, but does not brood permanently.

 Of course, she returns every evening.

We will have to wait until the 18-19 April, the 7th egg, for her to spend much more time in the nest. Weather is better, beautiful sun and 16°C. She leaves much later in the morning. He always sing, but disappears during long periods in the course of the day.
10 oeufsNourrissage

20 April: 8 white eggs, stained with brown red, arranged well. Now she broods, and she will brood alone. He comes to nourish her. He calls from outside and she answers by small "pips". Small quiverings of wings and tail raised for both, like future chicks when they beg their caterpillars. Then he enters the nest. She has the bill largely opened to receive the caterpillar. He does not remain and immediately sets out again to seek another billful. Weather is hotter (22°C).
22, 23, 24 avril: 9 eggs. 22°C. She leaves in the morning a short moment but quickly returns to brood. She arises in the evening around 17h to nourish herself, and returns towards 20h before the night.

25 April


Regarde oeufsCouve

10 beautiful eggs well arranged !

She broods.

26 April: common swifts arrived at Paris.

Now we recognize her better, her plumage is a few tousled and the feathers of the breast open to brood.


Chenille verte

Contrary to the great tits, it's indeed difficult, even impossible to distinguish the differences of plumage between Her and Him (less sharp color for Her, on the face and the wings? it is not obvious, even for an exerted eye). For us but, fortunately they see in the ultraviolet thanks a fourth type of cone cell in the retina. The difference of plumage of the crown (cap) is then clear in ultraviolet. And Madam, will prefer the male tit with the most brilliant blue crown. Here he offers her a yummy green caterpillar.


And she like he, for their splendid blue, fully deserve to be called "Parus caeruleus" (or Cyanistes caeruleus).

Mésange bleue

At the end of April, at the beginning of May weather is cold 5°-12° with rain and wind. She always broods. And she turns over its eggs periodically.

He, nourishes her. When he arrives he utter small chirps to call her, she answers and sometimes leaves to join him. Sometimes happens that he seeks her, while she is not in the nest. Then he enters the head, then a little more of the head, he remains at the entry, he hangs around… seems astonished. He concludes that he does not see well and enters the nest with its caterpillar. Definitely she is not there! Lastly, a small cry (like a little that of the swallows) but outside! Phew! He will not be obliged to eat its beautiful caterpillar.

6 May:  Beautiful sun, finally hot (25°).

 This morning, 7h the first chick!

Temperature is 15°C and the weather is overcast.

8h15 here is the second. 

He works. He enters with a caterpillar, which she takes to distribute among the chicks.

Poussin bécquée

She distributes the caterpillars brought by him,  to  the two chicks.

If she is not there, he takes care of the distribution. He remains with precaution on the edge of the nest to give the beakful.

Coquille d'oeuf9h 20 birth of the third chick. She assists it. Then, on several occasions we see her with a half eggshell, she eats the shells, because none remains in the nest and she needs to recover all the calcium of 10 eggs!


When he arrives, it is always with a yellow green caterpillar, that she divides. Sometimes she eats one of them. The small chicks have a large head which they do not yet  manage to raise. With enormous globular eyes still closed and down feathers around the eyes. Large yellow bills to receive the piece of caterpillar. They do not have yet the reflex to open the bill and she must move the billful over the small chicks to invite them to open the bill. They will learn quickly, in two days they will open the bill at  the arrival of one of the parents. Sometimes the billful is… a little large!




Quatre poussins

8 May

Rainy night, overcast, 15°C. The fourth is born this morning. A brood of 4 chicks all naked, all pinks. The brood is complete, the 6 other eggs will not hatch, perhaps because of the bad climatic conditions.

11 May:
The chicks grow very quickly. Their bills have enormous yellow moustaches.

12 May: Sun 22°. They do not see yet but are increasingly active. Four days and we begin to guess the quill of the feathers, in particular on the wings. She remains less in the nest and the supplying  is made by both parents.

14 May:
Beautiful caterpillar, for four yellow pits with their small orange points. The quill of the feathers grows and they are not more pink but dark now. They have 7 days. A chick starts already, to half-open the eyes, especially with such a beautiful insect!

15 May: Up to now the chicks were nourished with beautiful green, tender and fleshy caterpillars. Now the mode changes. In addition to the green caterpillars, more and more insects are supplied to supplement the meal. The eyes are half-opened.

 They grow bigger! Four beautiful “chickens”, which leave more and more the bowl of the nest and flap their wings. Their eyes are quite open.

As for the parents, there is the household...

Sortie sac

Sortie sacTo defecate chicks raise their bottoms. A small white bag comes out, the fecal bag, which she take and carry to throw it far outside avoiding all traces for the predators. Even soaked like this day!

Sortie sac



And, four great bills to be nourished...

 Many journeys in and out are needed!



And some acrobatics...

To bring back the menu... insects, caterpillar



At the beginning the menu of youngsters is exclusively made up of large quite fatty green caterpillars. Then, coleoptera, insect  larvae, flies and aphids supplement the menu.



Lastly, well later, some shelled seeds of sunflower and catkin seeds of birch, willow or poplar which abound at this period of the year.

The chicks, beakful after beakful, will become Mésanges…
