The Dehradun-Mussoorie trek: What I saw

Birds! Oh, so many birds.
Right at the beginning of the trek, when the path skirts the hill, there were several birds in the undergrowth. I am not sure if I could identify all of them, but especially common were the White Browed Shortwings. I also saw tits, and am reasonably sure some of them were the Green-backed Tits. As for the rest, I have an impression of greenish yellowness and of crests- the Black-lored Tit, perhaps? Red-vented bulbuls were there in plenty, and those I can confidently name. There were also a lot of olive-khaki clad little things. Warblers, certainly. But which ones?
Immediately past the steep bit, there is a flat stretch. And here I saw two Kalij pheasants, a male and a female.
On the wooded part of the trail, just when the ‘steps’ start, I saw the Slaty-headed Parakeet. I only saw one, but there were three of them across the valley calling out in turn- as if doing triangulation. A little later, I am fairly sure I saw the White-tailed Robin, male. Also saw a Velvet-fronted Nuthatch, very fleetingly as it flew across the path right in front of me.
Near Jharipani, where the path becomes paved again, I saw three eagles, but I am really bad at identifying them. Reading my bird book has left me inclined to Bonelli’s Eagle, but I wouldn’t bet on it. just how bad I am at identifying raptors, you ask? Well, on this trek, I thought I saw a Changeable Hawk Eagle in its dark morph, and was pretty proud of having identifying it. And then it landed on a branch and cawed. The only way of excusing myself is by hoping it was a Large-Billed Crow. Let’s move on..
Yes, do let’s move on, because now we come to the best bit. Earlier on, where all the warblers and shortwings were, I heard a rustling in the shrubs by the path and was excited thinking that it was caused by a flock of quails. Till I saw sunlight glinting on what could only be fur. A moment later, a deer stepped out onto the path and paused for a moment. No spots, excitingly backlit by the sun, it was a dull brown with silvery tips and that lovely silvery haze around its ears. One quivering breath from each of us, and it was gone! Lovely.
