After doing a lot of research I am inclined to believe that this is a Eurasian Griffon Vulture. I know that Tanzania is not where they are normally found but based on the color of the neck and head and the patterns on the wings it is the one vulture that fits. I am pretty sure it is not a white-backed because the feathers at the base of the neck are totally different. If my deductions are wrong please let me know.

I think I have been able to answer my own question I'm now pretty sure the first bird is a Brimstone canary and the 2nd and 3rd are Western Citrils. If these prove to be wrong I hope someone will let me know.

Thank you, it was an amazing trip.

These small weaver birds were in the Ngorongoro Crater in Tanzania. I'm pretty sure they are 2 different kinds of bird. I think the duller one (3rd picture) is a female of the 2nd picture. I thought maybe a slender-billed weaver but I'm not sure. Any help would be appreciated.

This photo is from a trip I took last month to Tanzania and was taken in the Ngorongoro Crater. I know the large bird is a Grey Crowned Crane but I cannot find what type of what I believe is some kind of vulture. The crane was doing it's best to scare off the vulture but it never even opened it's wings. Any help with this would be appreciated.

I import the pics with a 1:1 preview, medium quality, 3840 pixels (I have a 32 inch 4k monitor) and the previews are discarded after 30 days. There are so many files because I just got back from 2 big trips (Antarctica and Iceland).

If that is true then why are all the items I copy so much faster, this seems to only affect the LR previews?

I have a question about making a backup of LR preview files. (Yes I know that backing this up is not really necessary but it can save time) If I use file explorer to copy the LR catalog from an internal SSD to an external SSD (Crucial X8 4tb using a USB 3 port) it copies at speeds over 100 mbs but when the previews are copied that speed goes down to low single digit mbs or worse kbs. Is this because LR (or Windows) must convert these previews to a different file format or is there some other reason these files take so long to copy? So far copying 292000 previews has taken 24 hours and it says it will need at least 12 more to finish. Thanks in advance for any help solving this mystery.

There is almost no humidity in Antarctica so condensation is not an issue.

I just got back about a month ago from Muench workshop and if I didn't have my 200-600 and 100-400 I would have cried. At least 80% of my shots were with these 2 lenses. Maybe 15% with a 24-105 and 5 % with a 12-24. These are all Sony lens.
By far the majority of your shots will be taken from the boat and I found the 100-400 to be the best for taking landscapes (Mountain/Glaicerscapes). Everything down there is so vast that it can be overwhelming with shorter lenses. Even on the islands with all the new penguin safety protocols in place the long lens will be your most used. You may find the 24-200 to be the most useful in the zodiacs. One suggestion use at least a 3 shot burst with camera on manual with auto ISO to help negate the movement of the seas. We were blessed almost perfect weather so light was never an issue.
I'm sure you will have a great trip, definitely use a patch on the Southern Passage. Also if your leaving out of Ushuaia be forewarned that Aerlineas Argentinas is probably the worls's most unreliable airline so be sure to allow a couple of extra days for cancellations. Our flights changed about 8 times with the last ones only days before we left. We were supposed to arrive 3 days early and ended up 2 nights. If you arrive early the Tierra del Fuego area is beautiful on it's on, hire a taxi for a tour of the National Park it's only about $100. Adding a day in Buenos Aires on the way home is very nice as well, we used a guide service called Gyde & Seek and it was great.

Take both bodies, put the 24-105 on one and the Sigma 150-600on the other. Even though the animals will not fear you, you are very restricted to the paths and the extra reach comes in handy. I made the mistake of taking a 100-400 as my longest lens and at times would have loved to have my 150-600.
It is truly a wondrous place, enjoy and post the results.

Man, these birds look so much alike. The Dunlin is very close but they have a pure black bill while mine has a small orange spot. After looking at Ebird I am leaning towards a White-Rumped Sandpiper.

Ruddy Turnstones appear to have yellow legs so I don't think that it is one. Thanks for your prompt response.

I believe this a sandpiper of some sort, though you cannot see them in this picture it has black legs. The photo was taken in the Galapagos Islands on Isabella Island at Tagus Cove. Any help at it's identity would be greatly appreciated.

I was there in 2018 on a photography cruise with Tui de Roy. I would take the longest fastest lens you can, rent them if you need too. I took a 7dMk2 and rented a 5dMk2 the vast majority of my shots about 70% were shot my 100-400, if I were to do it again I would have taken my 150-600. The remaining 30% were with a 24-105. I also used an Olympus TG-5 quite a bit for underwater shots.
I hope you get to do the trip it is quite amazing down there.
