The end of a short story in life…

This afternoon the birdsnest outside my office window has been plundered by a crow or raven. Even though the parent-birds got reinforcement by two other fieldfares they never had a chance.

The small birds only had a few days of life but they somehow enriched my days.

…they just had a few days […]

BirdCam – feeding in slow-motion

Because there was a problem with the Raspberry Pi again today, I took the opportunity to film my fieldfares live for a short while. In this slow-motion video you can see how first the female arrives at the nest with a fresh worm. A short while later also the male arrives with a beak […]

Hatching time

“I’m hungry!”

Ten days Mrs Fieldfare has been sitting in her nest – today was the big day: until late afternoon three eggs had hatched. Now also Mr Fieldfare has to show some effort who has not been much around the nest lately.

This is […]

BirdCam v4

Touch down!

It took four attempts to finally get a suitable webcam to observe the bird’s nest outside my office window. Most cheap webcams, even those which show off with true 720p HD resolution simply cannot cope with the different outdoor lighting conditions over a full day.

After a lot of testing and research on the […]

Setting up webcam exposure under linux

I had some problems with fswebcam to set the automatic exposure. The exact way how to enter certain parameters is not clear from the lacking documentation, but it works fine if you set parameters through another command line tool.

This is the script behind BirdCam:

#!/bin/bash DATE=$(date +"%Y-%m-%d_%H%M") v4l2-ctl -c exposure_auto=1 v4l2-ctl -c gamma=5 […]

Fieldfare

Nils Paakkonen was probably right, my new neighbors outside the office window is a pair of Fieldfares.

This morning the whole family was at the nest:

First day with BirdCam

2016-04-09_1740_b

Last Friday I heard some strange noises outside my office window. To my big surprise I then noticed that there was a bird’s nest growing on the window sill. It did not take long until I even saw the new tenant moving in:

Outside my office window…

So far I have identified […]

A bicycle trip: all municipalities in Uppsala county – on a day

Uppsala county and its eight municipalities (map borrowed from the cache description).

There is a geocaching challenge in Uppsala: to visit all 8 municipalities in the county of Uppsala within 24 hours. When I first saw this challenge, I wondered if it was possible to do this by bicycle. I took a map and roughly sketched what would be the shortest possible route to travel to […]

Swedish midsummer flora

.

Today was the Swedish midsummer eve – and I used the free day for a bicycle ride. Hunting geo-caches also brought me in contact with nature.

Paris quadrifolia is quite common in the forests around Uppsala.

The day of the city forrest

Today was the Day of the City Forrest (Stadsskogens dag) here in Uppsala. For everyone who didn’t climb the 180 steps up onto the water tower, here is the view from the top (you will need Apple Quicktime to be installed):
