Trouble shooting for my elderly parents, they had a lower limb removed from their River Birch about 6 months ago and within the last month or so it has been leaking a yellow fluid. They are wondering if this is simply sap escaping now that the weather is warming up and things are thawing, or if there is a problem they should be on the look out for the tree such as some type of infection that could be causing it?

Sap. You could have googled this.
Yeah, you’ll have that on those bigger jobs
How will the remaining stems be affected by this? Will it cause girdling on the portion next to the removed part?
If you cut in the winter, like you should that was a good call , the tree is dormant for the winter. Sping comes, the ground unfreezes , water tries to go from the roots up into the tree and….that part of the tree isn’t there anymore.
It’s sap. The tree clotting, let it cook!
That’s a slime mold, feeding on the sugary sap leaking from the freshly cut stem. It’s harmless and will go away on its own.
Deer vomit.
Microbes feeding on the leaking sap. Normal.
