Great time to head to Mud Lake Conservation Area. The water side (the pond and lake on the south side of the Cassels' Road) tends to have the waterbirds, the herons (both mature and immature, ducks, turtles, etc.) and the north side (the ridge between Cassels' Road and the Ottawa River) seems to have all the warblers. Patience and binoculars, as well as a sound camera set up are essential.
Remember, even with image stabilizing lenses, you really need to shoot at the fastest shutter speed possible while keeping the ISO setting as low as possible to reduce digital noise in your images (higher ISO = faster shutter speed in low light but higher ISO = grainy, affected images).
Using a tripod is really critical. If you want to know why, try holding a laser pointer at a wall from 10 feet. Watch how the laser dot bops around, despite your best efforts to hold it still. Now, if you're hand holding a camera that weighs several pounds, and your tiny bird subject is in movement, your hand movement (remember the laser pointer analogy?) and the bird's movement will result in less-than tack-sharp photos; you'll get blurred images. I carry my camera, set to the lowest ISO for the ambient light, ready to shoot over my shoulder while mounted to the tripod. If I see a bird, I carefully bring the tripod down to the ground and set up and shoot, generally in seconds. Take caution, however, if you decide to carry your tripod over your shoulder with the camera attached. I use a very high quality tripod (Really Right Stuff) to ensure that I can do so without losing my camera. If you carry your camera mounted, all ready to shoot, make sure you have a safety strap around your neck or some other point of safety. Failure to do so may result in your camera suddenly detaching and crashing to the ground! Frequently check camera-tripod connections.
Chris Kiez, a hardcore photographer since the 80's, learned to take a picture before the age of selfies and cell phone photography, training on mechanical cameras and film. After years of taking photos of all manner of subjects and people, he did over a 10 year stint as a crime scene photographer on two continents. Now, he does portrait and landscape photos, and is currently distressing the world with his relentlessly, excruciatingly boring blogging. To buy what you see on this site, click here!
