- Filming Orchids with the Panasonic DMC FZ200 and FZ300 Cameras is a short video illustrating some of the advantages of using these cameras.
- They have a good depth of field which allows you to focus on tiny orchid flowers using the macro setting.
- I have found the lightweight Slik Sprint Pro II tripod very useful. Of special importance is you can focus on a flower take a short video and easily remove the camera to view how it looks and put it back without altering its position.
- For very tight areas the tiny AMBICO tripod works well.
- By using f 2.8 the orchid flowers can stand out from the background.
- With their regular batteries these cameras will run 1.5 to 2 hours in the video mode.
- Using a Juicebox DSLR Power battery and a Bescor Coupler & AC Adapter Kit for Sigma fp & Select Panasonic Cameras should allow these cameras to run in the video mode for many hours.

- We Really Like is a video showing some of the different creatures that eat and come to dandelions.
- I see lots of deer and bears foraging on them along roadsides in the spring.
- I wonder about the effects of salt on roads and whether the dandelions can accumulate the toxins and transmit them on to our wildlife. The same concern about the use of pesticides to control dandelions on lawns and the effect this might have on creatures that forage on these plants.
- For interesting information on the history of dandelions look at https://www.youtube.com/watch?
- A Great Blue Heron caught shows what fish the heron caught in about a one-half hour of filming.
- This could be a useful video to show while discussing the behavior of a heron while fishing.
- It appears it caught Pacific herring, juvenile salmon, a small flatfish, sculpins, and a gunnel.
- Of interest is one of the sculpins was probably a staghorn sculpin which because of its "horns", which it erects when disturbed, could be very difficult and dangerous for the heron to swallow. In the video you can see that the heron eventually gave up.
- Gunnels are also difficult for them to swallow -- not sure why -- perhaps the way the fish struggle or perhaps tough skin. In another video it shows a heron not being able to swallow several gunnels. Type in gunnel in the search to find the video.
- For a fun article about these birds look at Things that go Squawk in the Night (Great Blue Herons) by Bob Armstrong and Marge Hermans
- Hedgehog Arion is a small slug that was feeding on Wild Iris leaves in the Very Beary Berry Wetlands.
- The slug was identified as Arion intermedius by using the key in Slugs of British Columbia -- a key to http://www.ou.edu/cas/botany-micro/ben/ben320.html
- This is an invasive slug that seems quite common in Southeast Alaska. To learn more about this species look at /sites/default/files/Arion_intermedius_Gastropoda_Stylommatophora_first%20%281%29.pdf
- In this publication they mention: Its worldwide invasiveness is apparently facilitated by its feeding habits and particularly by its reproductive strategy of strict self fertilization which is unusual in pulmonates.
- The Value of Cow Parsnip for Insects in Alaska is meant to illustrate how certain plants attract a wide variety of insects to feed on their nectar and pollen.
- The Cow Parsnip is considered a "generalist" flower that attracts several species of insects.
- These types of flowers are (from the book Pollination and Floral Ecology by Pat Willmer, 2011 by Princeton University Press}.
- open accessible flowers, bowl shaped or flat;
- small or medium-sized flowers (very small examples often grouped together as inflorescences);
- commonly white, cream, or yellow-green in color;
- mild to moderate scents, fruity or musty but not unattractive;
- highly accessible pollen, often in large-quantities;
- exposed nectar, occurring at low volume and usually high concentration.
- This seems to fit the Cow Parsnip (Heracleum lanatum) perfectly.
- In watching the insects that come to various flowers I am always amazed at how many visit the Cow Parsnips. Even on cool rainy days.
