Nikon P900 offers a lot of zoom, but not all of it us truly usable. Still, out to 1800mm, it is surprisingly decent.
As far as overall image quality goes, it is decent for the price and for the reach you get, but ultimately very mediocre (Canon SX50 mentioned earlier is somewhat similar if not worse).
The decision really comes down to how much magnification you are looking for. P900, to me, has a very limited range of applications due to noise imaging pipeline and limited dynamic range. You need a lot of even lighting to make that long zoom lens work.
If I were buying a bridge camera today, I would be taking a close look at Panasonic FZ1000, Sony RX10 Mark II and Canon G3X. As an allround camera, the FZ1000 is probably your best bet for the money. All three do quite well, all things considered, in low light.
While none of these have as much reach as the P900, they actually deliver quality images in a variety of conditions.
To address another question i saw earlier in the thread: if you attach your cellphone to an eyepiece of a binocular, the effective focal length of your observation system is the equivalent focal length of the lens in your cell phone multiplied by the magnification factor of the binocular.
For example, if you are using a 8x42 binocular with an iPhone 6, the effective focal length you end up with is 8x29=232mm.
If you use your iPhone with a spotting spotter that can go all the way out to 60x, you end up with an effective focal length of 1740mm.
I like phonescoping (which is apparently a real term), but I use a much higher resolution Lumia 1020 phone for it, so I can get the combination to reach very far.
The biggest advantage of using a spotter or binocular with a cellphone is that digital cameras are not designed for observation, regardless of how much detail the camera may be capturing, seeing it on that small screen is difficult for any prolonged observation.
