Buzzard Cam 2016 ~ Mari and Mihkel

Post by Felis silvestris » March 3rd, 2016, 6:23 pm

Our wish was fulfilled, the camera which was installed last year at the nest of the buzzards Mari and Mihkel started working again today (March 3).

Let's hope that both return and choose this nest again to raise chicks.

About our buzzard nest

In 2015 the Estonian bird of the year was the Buzzard. In Estonia three kinds of buzzards can be encountered: the Common Buzzard (Buteo buteo), found in Estonian all year round, the European Honey Buzzard (Pernis apivorus) breeding in Estonia during summer and the Rough-legged Buzzard (Buteo lagopus) wintering in Estonia. For this occasion two Common Buzzard nests were fitted with web cameras to be able to follow the nest life.

The nest is in the Tartu area, in a commercial state forest. A train line is not too far and a farm (with one or more barking dogs) about 200 m away.
On this nest, which was camera 1 last year, we could follow the nest life of a Common Buzzard pair which got the names Mari (left) and Mihkel (right).

They raised three chicks: Maxi, Midi and Maimu.

Jürgen wrote about the history of the nest:

This nest was found in the spring of 2012 (at around 26th March) by myself. I suspect that at that year the pair had layed eggs already by that date.
In 2012, 3 nestlings were ringed in the nest. In 2013, 2 nestlings were ringed in the nest. During the winter between 2013 and 2014 a portion of the forest near the nest was cut down. In 2014, 3 nestlings were ringed in the nest.
The nest is in a spruce tree around half-way to the top (no official measurements have been made but I would say around 13 meters off the ground).
As we know, neither Mari or Mihkel have rings and ringed buzzards have never been spotted on this territory. Also something interesting I have noted about this pair is that they sometimes hunt quite far from their nest. I have spotted one of them nearly inside Tartu which means they went past at least one other buzzard territory.

About Common Buzzards:

Buzzards are medium sized birds of prey found almost all over in Europe and parts of Asia. The common buzzard measures between 40 and 58 cm in length with a 109–136 cm (43–54 in) wingspan and a body mass of 427–1,364 g. The colours vary from very light to very dark.
Buzzards become sexually mature with about 2 years and buzzard couples stay together a lifetime. They stay in one territory and can become up to 26 years.
Breeding starts in Central Europe from mid March, on average it is from around mid April. The female lays usually 2-3 eggs, size 56 × 45 mm weight 50–60 g. Colour white with reddish brown and greyish brown specks. The eggs are laid with gaps of 2 to 3 days.
Breeding time lasts 33 to 35 days, depending on the size of the clutch. Breeding starts later in bigger clutches.
The buzzard chicks stay for about 42 to 49 days in the nest before fledging. After that they will stay around the nest and will then follow their parents begging for food for around 6 to 10 weeks. After that they leave their parents' territory, but stay not too far away.

Eggs

The typical clutch of the buzzards consists of 2 to 3 reddish-brown to greyish-brown eggs, size 56 × 45 mm and weight 50-60 g.
The eggs are laid with a difference of 2 to 3 days, incubations depending on the size of the clutch. Incubation starts later in a clutch with 3 to 4 eggs than in a clutch with 1 to 2 eggs. Incubation time is 33 to 35 days.


1st egg: April 6, shortly before 11 AM
2nd egg: April 9, at 8:53 AM
3rd egg: April 12, around 8 AM

Chicks

Sadly the first chick, which started the hatching on May 10 did not manage to get out of the egg and died in the process.

May 12 - we could welcome the second chick shortly before 5 PM
May 15 - the last of the three eggs released its inhabitant at 11:30 AM

Names for the chicks:

For the female chick (which hopefully is there) Maret was chosen with 7 votes.
For the hopefully male other chick Martin was chosen with also 7 votes.

Update July 18: DNA testing shows that both chicks are male. Name for the second chick is changed to Marek

Great indeed to have this cam again!
It was a very happy nest last year. I hope that Maxi, Midi and tiny Maimu are doing fine, and that we'll see Mari and Mihkel soon. May you have good luck with mice and everything!

that sounded like boar to me: the sniffing and grunting and the quick pace of footsteps sounded like trotting of relatively short legs.
thank you Fleur!
(and a belated Happy Birthday! :loveshower: )
