As a marine ecologist I have a serious fascination for terrestrial ecology blogs, and I've stumbled across another stunner - Notes From Kenya. It's a blog written by Michigan State University students in the Holekamp Lab, about their experiences in Kenya as they research spotted hyenas in the field.

I've previously posted about Golden Rays here.
Here are some more photos, from the Telegraph this time:
A ranger in Kenya's acclaimed Mara Triangle wildlife park Kimojino is a member of the Masai tribe. He first learned how to click a computer mouse in November. Now he blogs about the Mara Triangle and posts wild animal photos on Flickr nearly every day. Kimojino's online outreach is an effort to raise awareness and money for the park, and it's urgent: Without the funds he raises online, his employer, the Mara Conservancy, would go broke. Admission fees from park visitors are the conservancy's primary source of revenue, but tourism dropped to almost zero during Kenya's post-election violence, and hasn't snapped back.The thing is though, it's a really great read. Updates are frequent, and Kimojino posts some amazing wildlife shots almost every day. At the moment the Wildebeest are massing on the banks of the river as part of their famous migration (see photo). Earlier in the week they arrested poachers armed with AK47's in the park, and blogged it. Last month the Zebra were migrating and the Crocodiles were feasting.
Working on a reduced budget for two months is starting to have an impact on the effectiveness of the Conservancy, and there are warning signs which indicate that the situation may deteriorate further. Our work is now threatened as a direct result of the collapse of tourism in Kenya. Due to lack of funds, all non-essential activities have been stopped since January, as well as the halting of the cattle compensation scheme and regular night patrols by rangers.
Tourist projection for the month of July and August is 50% occupancy. For the rest of the year it is expected to fall back to 20% like it has been up until now. This means that our situation will remain dire until 2009, however this is not an appeal for money (although if you have some it will help a lot) but instead we need ideas on how to fundraise for the long term. We thought that things would improve, which they have slightly, but unfortunately not as much as we had hoped.

...
The school was too large to photograph in it's entirety. Therefore, while flying transects across it, portions were photographed vertically...
The migration patterns, in the Atlantic, include a northward movement in the late spring and southward movements in the late fall. Southbound migration has been observed to contain larger schools than the northbound migration. Smith and Merriner (1987) believe that the changes in water temperature, coupled with sun orientation, may initiate seasonal mass migration. They also suggest that the southward migration might be influenced by solar orientation while the northward migration might be influenced by water temperature cooling below 22ÂșC, but further studies are needed to confirm this. The migratory congregation, thus far, has not been linked to feeding or premigratory mating activity.
