Birding as with any other field endeavor has its basic equipment requirements (binoculars, scope, field guide, notepad and pencil) in addition to all the ancillary things we individually "need" and stuff into our field jacket pockets and/or day pack. I have long suffered from equipment overload and digiscoping (the camera and spare batteries) has added to it. The number of times I have had a subject targeted in my scope and have fumbled to retrieve the camera and prep it to shoot an image only to have the bird drift out of sight or worse yet disappear altogether, well, are too many to want to remind myself of. With regard to storing the camera safely in the field and at the same time have it handy when needed most is something I have been looking at for a better solution.
I think I have finally found it. The camera when not in use is stored in a sturdy case attached by straps to one of the scope tripod legs (Figure 1 below). The case is a Model 1010 Micro manufactured by Pelican Products. It is strong, durable and water resistant. The interior is padded with a rubber insert that accepts a camera having maximum dimensions of 4" x 2.5" x 1.25." The case snaps firmly shut and is moulded with two belt loops. Two 24" long, 3/4" wide nylon straps each fitted with a ladder-type slide buckle at one end are used to amount the case to the tripod. Total cost of these items is less than $20 (case $15; straps $2.50).
Assembly of the components and attachment to the tripod is simple. Connect the two straps by the buckles end to end to make one continuous loop. Insert an end of the doubled over strap through one of the belt loops and repeat for the other belt loop (Figure 2). The strap should extend between the two belt loops across the back of the case. Stretching out the strap creates a figure 8 (Figure 3). The strap loops are then slid over a tripod leg and cinched up real tight to prevent the case from sliding off or moving sideways. I found that attaching this to one of the legs with a foam hand grip provides the greatest stability.

Advantges of this setup are: (1) you know exactly where your camera is and is handy to get to when you need it, and (2) when stored in the case it is protected from bumps, scratches and moisture.
