Cowbirds use an interesting approach to egg laying. No time is watered to build a nest. They expend all their energy laying eggs. But only in the nests of others. The bigger chick usually wins the battle against smaller fledgelings from the parents actual offspring. They are all raised by adopted parents often at the expense of their own breed. The most common “Brood Parasite”
The network of 29 (currently) Game Trail Cameras that I run occasionally come up with some pretty candid captures. I don’t recommend any brand of Game Trail Camera as all of them have their share of unique problems.
This capture was from mid summer 2019. We just at a Blizzard (a week ago as I post this) There are Game Trail Cameras that I won’t be able to get to before spring already. I had pretty good batteries and typically they can go 6 months unless something is overstimulating the shutter. Moving branches or grass can set your Game Trail Camera off eliminating your battery or SD card’s capacity. Which ever comes first will be the end of that camera.
I do have to remember where I have put cameras. This is a very big place and I’m sure there are a few out there than I don’t remember but I eventually will run into them. This is a very big place at 5.5 square miles. But it’s a small ranch compared to others around hre. It’s a matter of scale which is very hard to convey. Folks that have visited here fully understand.
At midday when the sun is shining brightly, look for soaring “kettles” of Sandhill Cranes Riding Thermals over grasslands. These groups appear as barely visible wisps from afar with the unaided eye.. I think there is around 300 here…(Rough guess). Circling, right side coming at the camera the left side going away in the spiral.
The birds are using the thermals and keeping their flight muscles toned for the journey that lies ahead. Off to Nebraska First where they gather by the thousands on the Platte River where they put on some fat.
Several species of Sandhills (at least 6) with 3 being non-migratory and the rest are migratory. Cranes are diurnal or daytime migrants and use thermals to their advantage. They will hitch-hike a ride with the thermal higher and higher up to an altitude of a few thousand feet. They then will glide southward in wavering lines losing altitude as they go until they reach the next thermal, spiraling upwards to repeat the process. Rinse and Repeat is the play of the day. This method of migration is highly energy efficient, more so than the powered heavy on-flapping flight of other species such as the Canada Goose… On a good day with the right thermals, cranes can travel up to 500 miles but 200 to 300 miles is more typical. Finally in the late afternoon, they seek a wetland of some type to noisily roost in for the night. They depart the next morning with weather permitting, until they reach their next destination on the journey.
This Flock was following along the back edge of a snow storm that lasted a day. They were clearly waiting for it to move on so they could get past it and hung out just circling round and round getting higher with each revolution. Eventually they headed south toward the back of the snowstorm visible in the distance only to find another thermal and jump on board.
Location: Somewhat over the Bliss Dinosaur Ranch, Wyoming/Montana Borderlands.
