  • Urban Green Space Management for Invertebrates and House Sparrows
    Urban green space management for invertebrates and house sparrows Jacqueline Elizabeth Sarah Weir Imperial College London, Department of Ecology and Evolution A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy May 2015 1 Declaration of Originality I declare that this thesis is my own work, other than where appropriately referenced.

Productivity can be increased by providing invertebrates (Peach, Sheehan & Kirby, 2014; Peach et al. in press). This study tested the effectiveness of three habitat treatments in increasing invertebrates and seeds in London parks, and their usage by house sparrows. Treatments were: annually sown ‘wildlife seed’ plots; sown perennial wildflower meadows; and existing grass grown taller. Treatment establishment and seed abundance were assessed by vegetation measurements, and practicality qualitatively assessed through questionnaires. Invertebrate abundance and variety were measured using sweep netting and vacuum sampling, and relationships tested with treatment type and modelled air pollution levels.

  • Homemade Bird Food Recipes by Susan Kelly
    Homemade Bird Food Recipes By Susan Kelly Contents Introduction Why Make Your Own Bird Food? Seeds and Grains for Birds What is Suet? Suet Recipes Fruit Bird Food Recipes Nectar Recipes Bird Food Crafts Introduction My first experience feeding wild birds was tossing breadcrumbs to ducks at the town pond. I was very young, but I can remember that feeding one duck quickly turned into feeding 20 ducks. I don’t know if I realized it then, but I learned that birds are drawn to areas where other birds are feeding. You can see this for yourself by placing a few bird feeders in your backyard. I set up my first bird feeder about 10 years ago. I can remember it seemed to take forever for the first bird to arrive. But once the birds found my feeder, it was just like the ducks when I was a child – more and more birds came every day. I was filling that bird feeder almost daily. So naturally I added more and more feeders. I was attracting chickadees, nuthatches, wrens, juncos, sparrows, titmice and a few woodpeckers. I was happy with all the activity around my feeders, but I knew there were other birds in my area that were not visiting my feeders. I had seen blue jays, mourning doves, cardinals, hummingbirds and pileated woodpeckers. So why weren’t they visiting my feeders? I discovered that different types of food attract different types of birds. I began buying different types of bird food only to discover that in some cases they required specialized feeders.

    STRATEGIES TO PREVENT AND CONTROL BIRD FEEDER ASSOCIATED DISEASES AND THREATS CREATING A WORLD THAT IS SAFE AND SUSTAINABLE FOR WILDLIFE AND SOCIETY CREATING A WORLD THAT IS SAFE AND SUSTAINABLE FOR WILDLIFE AND SOCIETY Strategies to Prevent and Control Bird-Feeder Associated Diseases and Threats Contents Main Messages 1 Background 1 Management Cornerstones– The ABC’s of Healthy Bird Feeding 2 Avoid Unintended Consequences 2 Be Vigilant with Surveillance 3 Contact Reduction 5 Summary 9 References 9 Prepared by the Canadian Wildlife Health Cooperative Scott McBurney, Craig Stephen, Dale Jefferson, and Patrick Zimmer December, 2017 www.cwhc-rcsf.ca CREATING A WORLD THAT IS SAFE AND SUSTAINABLE FOR WILDLIFE AND SOCIETY 1. Main Messages • As the popularity of supplemental bird feeding increases, so too have the extent and frequency of infectious bird diseases that are suggested to result from increased contact between birds at feeders and contamination of the feed or feeders with infectious organisms. • Surveillance alerts the public to the need for action, helps management agencies assess the species affected by and geographical extent of outbreaks and can fill information gaps needed to understand the ecological impact of diseases. • Control measures center on reducing contact between infected birds and range from avoiding supplemental feeding through creation of bird friendly habitats to proper bird feeding techniques including appropriate choice of food combined with proper feeder selection, placement, cleaning and disinfection. • Proper feeder placement can also reduce risk of unintended consequences of bird feeding, specifically predation and traumatic accidents. 2. Background The impetus for this report was the widespread trichomonosis outbreak in the summer and fall of 2017 that extended through every province from Ontario east to Newfoundland and Labrador (CWHC, unpublished data).

    Wild Bird Feeding Guide - HOW TO ATTRACT WILD BIRDS - WHAT’S IN A SEED - FREQUENTLY ASKED QUESTIONS - TYPES OF FEEDERS - CHOOSING A FEEDER - HOW TO PROVIDE WATER - WINTER FEEDING - SQUIRREL SOLUTIONS Attracting & Feeding Birds HOW TO ATTRACT WILD BIRDS: • Position feeders so they are visible from your window but not out in the open. Birds are shy creatures, so place feeders in an area that offers close cover, such as shrubbery or trees. • Each season has its own bird varieties. Bird feeding is a year round hobby. By providing food, shelter, and water for birds year round, you’ll see the largest diversity of bird colors and behaviors! • Different seeds attract different birds. Start out with an all purpose mix, such as America’s Favorite Elite. As you pick your favorite birds, a more selective bird food mix may be preferable. • Wild Bird Care is often overlooked come winter. When the weather turns cold and harsh, birds’ survival skills are put to the test. By providing clean bird food, shelter, and fresh, unfrozen water, your backyard will become a bird sanctuary all year long! • Squirrels if you can’t beat’em--feed’em! Today, many backyard bird feeding enthusiasts are also feeding the squirrels. There are many specialty feeds and feeders for squirrels (Prince Wildlife Formula). Place the feeder far enough away from bird feeders to deter them from disturbing your feathered friends. DID YOU KNOW • Backyard bird feeding is one of the fastest growing hobbies, second only to gardening. • The typical backyard bird weighs less than two nickels. • Backyard bird feeding is proven to be a great stress reducer & can add a positive note to your day.

As I got closer, I saw that the moth was really a Black- chinned Hummingbird injured in a collision with a large plate glass windows. The bird was still breathing, though it barely stirred as I picked it up from the ground. I cupped it in my hands and walked over to sit down in the shade of a large tree. I was struck by the senselessness of a tiny bird falling victim to our built environment. After a few minutes, the bird opened its eyes. Ten minutes later it was able to perch on my index finger. After half an hour it was actively looking around. It gave me a final look, then zoomed up to perch in the top of the tree. The bird was gone, but it seemed to have left me with a message, and perhaps a calling. At once fragile and resilient, this little being had stirred within me a desire to help birds thrive in a world increasingly dominated by buildings, pavement, billboards, and the material trappings of our everyday life.

  • Wild Bird Factsheet
    FACT SHEET Can All Wild Birds Eat the Same Foods? The range of wild birds that come flocking to our gardens is enormous and despite what some may think, they do not all eat the same foods. Each bird has different nutritional requirements and feeding styles based on elements such as: size, weather, season, habitats, and life-stage. Birds are also very selective feeders; they know what they want and will throw other seeds out of the way in order to find the food they desire. The type of food available is one of the main factors in how a bird chooses its habitat. Some of the most common species of wild birds and their feeding habits Robin Blackbird Robins are naturally ground feeders, and will eat a variety of foods In the wild, the blackbird will eat both including worms, seeds, fruits, and insects and plants, with much of their diet insects. The majority part of the consisting of worms, beetles and spiders. Robins’ diet is often determined by the Due to their natural diet, the blackbird’s seasons, insects in spring, berries and fruits in instinct is to forage on the ground, digging summer and autumn and then in winter, Robins will through the undergrowth to find food, and won’t often eat whatever food they can find. come to hanging feeders. As well as insects, Birds with a similar diet include: Dunnocks and blackbirds are also keen on berries, seeds, and Wrens. fruits. These take up more of the blackbirds’ diet in Autumn and Winter when there are fewer insects Goldfinch about.
