Waterfowl and Shorebirds

Video:  Eurasian Oystercatchers Incubate their Eggs

From the website:

The Eurasian Oystercatchers Haematopus ostralegus usually breed on the ground in open areas. The concept of roof-breeding is known from different sites. Aberdeen in Scotland is known for its population of roof-breeding Oystercatchers, counting about 230 pairs in 2004. In other countries the phenomenon is more uncommon, but is recorded (at least) in the Netherlands, Belgium, Finland, Latvia, Germany and Norway.

The Oystercatcher is one out of very few shorebirds that actually feed their young. This is also a condition for successful breeding on roofs up to 30 meters above the ground. In Bergen the adults feed in the parks near the building where they breed, and bring the food for their young. It seems that they mainly deliver Earth-worms Lumbricidae sp. to the chicks. The chicks stay on the roof until they are more or less able to fly.

Im not familiar with this oystercatcher, but the American Oystercatchers incubate their eggs 24 to 27 days.

Video:  Oystercatchers Have a Little Chick

While Mother incubates the second egg, Father brings a tiny worm, which he gently offers to their chick.

Hmmm, beans, about how old is this little cutie? If the other egg is still to hatch, he can't be too old right? He certainly is very mobile for being so young I think. I do not know a thing about these birds but was just wondering. Thank you for sharing once again.   :heart

Lovely videos, beans. It is so different seeing a  "precocial" chick after following the eaglets and their slower development.

I'm not sure if this is the right thread.... (there is another for Common Loons but specifically Minnesota) I've been watching and waiting for the BRI Maine Loons to nest at this site for a couple of years now. They keep coming close and their wails and mews and yodles are incredible. The cam is lovely to have on in the background too. Occasionally a Muskrat swims by also.

Here is a long sequence of about 60 frames (15 seconds apart) of a visit at around 2:09 pm today.



The webcam is on www.briloon.org website. The Loons are even now swimming close by and occasionally calling.

Edited to add: I started a new thread for these Loons

I'm glad to see this cam working.  You can make a separate thread for the BRI Loon cam, if you wish.  :ecsmile

Thanks for the suggestion, beans, I did just that. I didn't know if we should keep some categories together. Now I've probably upset the system by posting the animation twice.. so if you want, delete the one from here, except that you and Cawatcher have responded...   :blush

Video:  Mom, I want to sleep in


Around 4:15 AM in Bergen Norway, and two of the three baby gulls are ready to start the day with Mother and Father.  The third seems a bit reluctant.  Hes very comfortable under Moms warm feathers.

Thank you beans - cute. It's unusual to know anything about gulls or pigeons  :puzzled2 even though they are so commom. I tried the link you quoted and it went to a refresh image, but there was a link to the live cam http://tjeldcam.uib.no:24002 but I didn't get any sound. I will try again tomorrow.

Video:  Rooftop Oystercatcher Incubates her Eggs

Kjellaug and her mate Kjell are back at their rooftop nest in Bergen, Norway. When Kjellaug returns to the nest, she gives the cam a few good pecks before settling down on her eggs.

Recorded at 7:37 PM local time

Norwegian name: Tjeld

Haematopus ostralegus

The Eurasian Oystercatchers usually breed on the ground in open areas. The concept of roof-breeding is known from different sites. Aberdeen in Scotland is known for its population of roof-breeding Oystercatchers, counting about 230 pairs in 2004.

The chicks stay on the roof until they are more or less able to fly.

Oystercatchers have been breeding on roofs in Bergen city, western Norway the last five years (since 2000). In this period at least three different roofs have had breeding birds."

That's neat beans, haven't seen that cam before. The live cam didn't work for me but thinking it's dark there now.
