My photography which laid dormant after college was reignigted when I started birdwatching. First it was utilitarian. Don't know what that bird is? Grab a picture of it to try and identify later. As my enjoyment of birdwatching deepened, I began "hunting". Hunting for the photograph of the birds I saw.
The number of birds on my life list is now 828 and I have just over 225 birds in the gallery. I have more photos, some to be added and many others ultimately rejected due to display quality. How high can I take this? That's what my wanderings (and my OCD) will determine.
