In early January, 2019, I visited several of my favorite places to see wild birds. All of these locations have been heavily altered by human activity.
Here in Ritto City farmers have been preparing fields for spring planting. Often we can see birds in freshly cultivated fields.
Tree sparrows feed in and around fields and perch in trees that have been planted along a nearby road.
Some reservoirs are surrounded by woodlands that attract many birds, including cormorants, egrets, and herons.
Sometimes birds appear in places that seem hostile to nature. For example, on January 7th two white wagtails wandered into the ground floor space near the vending machines and restrooms at Terhara Station (手原駅) in Ritto City. One even walked into a restroom. These birds were much more relaxed around people than wagtails out in fields.
Some parks superficially resemble natural environments with streams, ponds, bushes, trees, and ground cover. Birds take advantage of such environments.
Unfortunately, grass or other ground cover is often destroyed by human activity or cut too short to support many insects and other small creatures. This loss of biodiversity hurts bird populations. Nevertheless, even athletic grounds and ground golf courses can provide feeding grounds for some birds.
Some artificial environments attract birds by accident. I often see a grey wagtail at an irrigation canal near my home. This bird sometimes perches on trash.
At Lake Biwa gulls perch on posts and other artificial structures.
Even the Yasugawa riverbed has become an artificial environment from which natural vegetation has been stripped away. Egrets, herons, and cormorants congregate out in the open, but they also make use of vegetation along the riverbank and nearby bridge foundations.
To some extent birds can adapt to habitat alteration and make use of artificial structures, but they still need food and shelter. If we continue to destroy habitats in which they can thrive, they will disappear.
