Which computer is best? Same question, really. You need to get the one that feels and seems best to you based on what you'll do with it. If you shoot lots of video and you want an easier to hang onto camera body that will have you lean one direction. If something "just looks odd", about one camera you'll never be truly happy with it. I agree with most respondents here that you really can't say either one is better than the other on a brand alone basis as to what their cameras are capable of doing. You need the one best at doing what you demand from a camera that looks and feels best closest to ideal in your estimation. You're limiting yourself by only looking at two makers - but you're limiting yourself to the two equipment makers representing the majority of serious photographers on the planet...
This is coincidentally also taken with a D3200 with AF-S Nikkor 55-300 lens; setting on close-up/flower icon on tripod with AF on and VR off, self-timer @ 10 second delay to allow vibration to settle. Not a premium lens or especially hi-res capture but simple to shoot using only auto settings built into the camera. I've shot both ways and on tripod VR off gives me better results.
I'm not a "...great bird photographer," by any means, but as a naturalist and bird specialist I offer the folowing. If you are a regular feeder at a fixed feeding station you can easily condition birds to come by calling by mouth each time you fill the feeder. Here in West Michigan, I simply make a "tsip tsip tsip!" sound every time I go to the feeder and the local chickadees, nuthatches, finches, and titmice come flocking in to feed. Cardinals, jays, doves, juncoes, woodpeckers and others typically follow soon after. This conditioning takes only a week or so if you're consistent (and you don't mind others who overhear thinking you're a bit goofy), and transient birds will quickly follow the locals as part of a 'foraging guild' association. Obviously this doesn't help much away from your regular feed station except in the springtime when most territorial breeding birds will respond to any squeeking or chirping sound you make which mimics their calling cadence; this is the "pishing" which birders refer to. A small friction squeeker call (the so-called Audobon call), will often attract curious birds as well. I have found recorded electronic calls to be more trouble than they're worth, with the possible exception of owl vocalizations used at night - in any case, play them at a lower volume than seems right. Birds are curious and have exceptional hearing and too much volume amplifies artificial and electronic noises, too. Hope this helps you out, and good luck!
Thanx for the share - lots of stuff here I either diddn't know, had forgotten, or never really considered. It's bookmarked for me.
Setting your sound defaults to give you reading and finishing tones on your built-in card reader is probably a good idea, to make sure you don't damage tha card.
You might also consider hunting around for a 'white box' unit. I've purchased new Nikon lenses for refurb prices from reputable dealers who do sufficient volume to have parted-out kit items available regularly. These are available from licensed dealers often and are fully factory warrantable. Do your homework first before refurb (or white box), though. Good hunting and good luck!
