Thanks! The first part (in good light) was shot with the Nikon Z9 with the 800mm lens on a tripod. The second part when light was very low I switched to the 400mm f/4.5 lens on a Z8 and was handholding. These cameras are very good at video, even in the hands of an amateur like me.
That's good to know. Thank you for your response.

Was very fortunate to spend some time at a GGO nest in British Columbia last week. Put a couple clips on Youtube for those who love owls:

Awesome video ! Was this shot with a dedicated video camera or with a digital camera (DSLR or mirrorless) and with a telephoto lens. Thanks

I also posted this in Links and Resources but it seems no one watches that section. Admin may kick it out of this area but if they do, I hope they will find a way to boost readership of the Links and Resources section. A lot of good info about deals and training could be overlooked otherwise.

Made by which company is this CFExpress card that you saw on B&H ?

Nitrogen, an inert gas, is nothing more than dry air with the Oxygen removed. The majority of "air" already consists of Nitrogen (78% by volume). The other elements of air by volume are 21% Oxygen and 1% other gases.
Most passenger cars have been designed and tested to deliver their expected performance when inflated with "air" and the correct tire inflation pressure is maintained on a regular basis.
The use of Nitrogen to inflate tires is not recommended for normal use; however, the use of Nitrogen is also not prohibited.
There are certain applications where Nitrogen inflation is advisable, i.e. in abnormal environment where wheel and tire overheating may occur such as in aircrafts, space shuttles, military vehicles, off-road trucks, and race cars. In these applications, the non-flammable Nitrogen can reduce the risk of fire, because Nitrogen does not support combustion and does not add fuel to the fire.
The physical properties of Nitrogen may reduce the inflation pressure loss only from the tire material natural permeability (diffusion through rubber). However, similar to air, Nitrogen can still escape from other sources of inflation pressure loss such as from wheel, wheel/tire interface, valve, and valve/wheel interface.
The most important thing for the customers is to maintain the correct tire inflation pressure on a regular basis as recommended in the Owner's Manual. Under inflated tires can reduce road holding, increase hydroplaning risk, increase road hazards sensitivity, reduce tire life, increase fuel consumption, etc.
If equipped on the vehicle, always reinitialize the Flat Tire Monitor (FTM) or reset the Tire Pressure Monitor (TPM) after the tire inflation pressure has been corrected.

I like this from one of his quotes about our only earth - a pale blue dot,
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every h****r and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

....as i was driving to our daughters house in Rainford StHelens England yasterday.The download helps the full view. 
Excellent landscape image and nicely captured. I am not sure if it just me, when I downloaded the picture, about one third from the top of the image there is a light horizontal line. Not sure what it is ? but thought I ask if you noticed it. Thank you.

After 6 days in Haines, AK we always like to spend a few days in Juneau to round out our visit and unwind. We were at the Mendenhal Glacier because we have gotten many eagle shots there and this day was no different. But we did see a GBH on the roof of the visitor center and as my wife walked up to check the hours, the bird flew off. Here are two of the resulting images.
Awesome capture ! Well said that is not a usual GBH shot. Nicely done.

Have many suggestions for you; how many places have you elected to visit so far?
Still doing my research. But at least 5 places in those 5 days.

Planning to take the CAT from Bar Harbor to Yarmouth Nova Scotia in later May/ early June. Going to be driving around in NS. Will be there for 5 (five) days only . What are the places to go ? Is PEI and Halifax around driving range and can it all be done in just 5 days ? Taking my R5, 100-500, RF800, 100 RF Macro, 5DIV, 16-35 f4. Interested in photographing birds, nature and landscapes like coastal sceneries. Also let me know places where to stay and food joints. Thank you.
