A breeding bird atlas is a special kind of book. For the nature lovers and birders who participate in breeding bird surveys, the atlas represents hours, often hundreds of hours, of volunteer time spent within a community of citizen scientists doing what they love, observing birds. So, what exactly does a breeding bird atlas contain?
Fish and Wildlife Service has listed the “Rufa” population of Red Knot ( Calidris canutus rufa ) as a threatened species under the Endangered Species Act (ESA). The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia. Photo: Ron Knight.
It is that time of year again when we start to see the shorebirds around Broome change into their beautiful breeding plumage. The header above is of several species of shorebirds on Reddell Beach. The Pacific Golden Plover are a good example of this. There are a number of shorebird species here for you to identify!
You can’t say the same about migration: you can’t say that every book about birds is necessarily about migration, for the simple reason that only about 4,000 bird species migrate (with some 1,800 of those traveling long distances). (Well, purely physical attributes play a part, too: they’re pretty good looking.).
Birders normally care about species and make species lists, how do families fit into those? Adding more species brings a lot of excitement, as long as you bird your own country or a continent. 11,000 species require lots of money and a good portion of one’s life. That gamble is rigged, so the house always wins.
There I found a study which showed that the ingenious little birds had found a protein source that allowed them to coincide their breeding with times of man-made, rather than natural seasonal abundance. For example, the Nutmeg Munia, Lonchura punctulata , has managed to maintain a presence in California and Florida for some years.
It is also known for the 500 exotic species of animals and plants that now call the Sunshine State home. Exotic species are animals that did not historically occur in Florida. One such species is the familiar mallard (Anas platyrhynchos). The New Zealand Grey Duck is nearly extinct as species. What Is Being Done?
The least common species of hummingbird I see here is the Calliope Hummingbird ( Stellula calliope ). To see the best example of this phenomenon, check out Wally Rufous’ photo here. She will begin breeding in April. She is the latest of our local breeders, not nesting usually until mid-May. www.youtube.com/watch?
Oriental Plovers Charadrius veredus are a species of shorebird that we see in varying numbers around Broome and they may be on the beach, feeding on insects across the plains or at the ephemeral lakes. Here is an example of a roost site along Eighty Mile Beach to the south of Broome in February.
Over the next few days, the Alpine Accentors ( Prunella collaris ) will arrive on their high-Alpine breeding grounds – it is time to start singing, despite that the treeless Alpine landscape is still under metres of snow. all Alpine Accetor photos digiscoped (c) Dale Forbes. all Alpine Accetor photos digiscoped (c) Dale Forbes.
But, to paraphrase Monty Python, every species is sacred. Conservation of migratory species must be an international affair. No matter how much we do to protect the breeding grounds of Neotropical migrants, we can’t assure the safety of those species that lose essential wintering habitat.
Insects and a host of other invertebrate life have evolved with these plant species, and thus depend on them. The latter figure very significant when you remember that many breeding passerines depend on the humble caterpillar to feed themselves and their offspring. Locally native plants are the base part of the local ecology.
Of course Africa could not to be left out of the pink weekend so I have researched all African species whose official or alternative names include the word “pink”. Great White Pelicans showing the pink flush of breeding plumage. Another not very pink species is the Pink-footed Puffback. Pink-throated Twinspot.
Terns of North America covers 19 species of terns, noddies, and skimmers that breed and are regular vagrants in the United States and Canada (like many books titled “North America” the geographical coverage stops at the northern end of the Mexico border). .” Note that these are not all species accounts!
My target at the start of the year was 200 species in the UK and 300 in Europe, so I’ve achieved the latter, while the chances of reaching the former are pretty good. That trip was fun, as it reminded me of the delights of watching birds like Golden Plover and even Meadow Pipit on their breeding grounds.
For example, the platform overlooking the heronry – initially, there were no benches (nor in any other of their hides), so I commented to the provincial Secretary for the environment (he is a birder and I know him personally) and he forwarded those suggestions to the reserve management.
Before my first trip to the tropics many years ago I always wondered how is it even possible that new bird species are discovered with all the deforestation and general habitat obliteration going on all over the world. I mean, we as a species are today basically everywhere. But still new species are found.
For, in birder lingo, a split occurs when subspecies are determined to be, in fact, entirely separate species. If you happen to have seen both species, your life list can increase without you even leaving the house. Two former species can also be joined into one, the same way. And there was great rejoicing thoughout the land!)
For example, when Corey gets the thrill of seeing a Black-throated Gray Warbler in Queens County, New York, he can be almost 100% sure that he is seeing a one-time vagrant, and not a previously undiscovered population. These are only a few examples of the many I could mention. They were probably not preparing to go south.
Black Drongos must be breeding here – this juvenile was terrorizing his parents with constant calls for food. For example, one cat is named “damao” (“big cat” in Chinese) while another was named “xiaomao” (“little cat”). Black-tailed Gulls , I think.
Of course, the California Condor is listed as “endangered” under the Endangered Species Act (ESA) and it has been famously subject to some of the most ambitious conservation efforts (including litigation ) ever undertaken for a bird. One management tool used by FWS is reintroduction of an endangered species into its former range.
Even better, just a few meters away from the food vendors, it is not too crowded, and the palm trees attract a number of birds, including two species of parrots. That is mainly the Philippines, as indicated by the species name lucionensis (Luzon is the Philippines’ biggest island). The first one is the Blue-naped Parrot.
, I noticed that many birds had moved from setting up territories and breeding to feeding chicks, I thought it would be worth sharing some more observations. Although I once saw a group of Barn Swallows pass overhead a few weeks earlier, these birds were clearly on passage only as there was no sign of this species since.
One such example is “pewee” Pewee sounds like something small, something seemingly insignificant but with a certain degree of charm. In Costa Rica, we have our pewees, 6 species of them. A common bird of hot, tropical habitats, it is very much an edge species. This appropriately named bird is just what its name says.
- Chinese proverb attributed to both Maya Angelou and Lou Holtz While spring in New York City is great for birders because of the wide variety of colorful migrant birds moving through it is equally enjoyable because of the birds that return to their breeding territories and let everything within earshot know that they are back.
Our big month of bird movements in Costa Rica, the 10th month of the year, is when most of the swallows, Scarlet Tanagers , thrushes, and other species on the South American express push through. How do they compete with resident species? In October, it’s what’s happening in Costa Rica. What do they eat?
While these birds are very much liked by Chinese birders, the species could unfortunately not be named the National Bird of China as the Latin species name of the bird is Grus Japonicus. It is not quite clear why they do this as it apparently does not affect breeding success. A nice example of gender equality of sorts.
This sort of biozone mixing can create a tremendous richness of species. Each of these habitats attracts its own group of species. Blue-black Grassquits , for example, depend entirely on the brushy grassland shown above. Among those are Sulphur-bellied Flycatchers , a species I love. This one was a true lifer for me.
Here are some things I’ve learned from the Peterson Reference Guide to Owls of North America and the Caribbean by Scott Weidensaul: The Burrowing Owl is the only North American owl species where the male is larger than the female, albeit, only slightly larger. The 39 owls include five endemic Caribbean species.
Originally considered monotypic, two species are now recognized. Drakensberg (or Orange-breasted) Rockjumper is a Drakensberg Mountain species whose range is shared with the tiny landlocked kingdom of Lesotho. Males of this species are more brightly colored in their non-breeding winter plumage. the Rockjumpers.
Nothing against the Rocky Pigeon but let’s be honest, if a breeding plumaged Blackburnian Warbler hops into view, It’s pretty easy to forget about that pigeon, Warbling Vireo , or even a Pine Warbler when you can treat the good old retinas to a striking combination of red-orange, black, and white. .”
When I got back into birding about six years ago, I would not have predicted the personal bonds a birder can form with certain species. While all birds bring us joy, and we certainly want to see as many as we can, some species just seem more… special. I’ll start with two species that are especially hard to find.
The feature distinguishes birds from other species; All birds have them, no other species do. Beaks vary across different kinds of birds, and this great diversity in beaks is part of the great diversity of the 10,000+ species of birds that exist today; Beaks thus facilitated the diversification of birds. So how did beaks evolve?
For example, years ago, Eiton Tchenrov postulated that the wild progenitor of the domestic dog, some subspecies or another of wolf, could benefit from overlapping its breeding territory with human hunters. It turns out that there is an example of this with wading birds in the Florida Everglades.
Seychelles’ small landmass combined with geographic isolation results in few species. For example, the main islands are the world’s only granitic ocean islands and at 750M years of age are also the world’s oldest ocean islands. That antiquity produces a high level of endemism, e.g. 19% of 62 breeding birds are endemic to the islands!
Lepidopterists, botanists, and herpetologists, that is, those who like butterflies, plants, and reptiles and amphibians, are drawn to the pine barrens by a host of species that either can be found only there or are found in great numbers there because of the huge areas of good habitat.
It’s a long drive, at least an hour of steadily climbing twists and turns; but there are high-altitude species I can only see there. I was not disappointed, as four FOY (First Of Year) species turned up. So why am I focusing on that species in this post? So eventually, the pilgrimage must be made.
Counting the Birds I was in my teens when I undertook my first bird-survey: it was field work for the British Trust for Ornithology’s The Atlas of Breeding Birds in Britain and Ireland. The breeding and wintering birds of Britain and Ireland. I didn’t, for example, see a single Fieldfare anywhere.
One of the ways I could describe the unique mix of birds I can see here in southwestern Mexico, would be to divide our species into five categories. The invasive species are few, but, unfortunately, very numerous. But there is a final group of species here, about which I have not written very much.
I pointed at the bird shown below but he insisted it could not be that species – no long tail … For people of a certain age, gender and background, at some point The Smiths were the most important band in the world. Other species, such as this juvenile Light-vented Bulbul , seem to have more ambiguous feelings about molting.
“The birds” as a whole will be “fine” but many individual species will not. Their remarkable survival skills, evolved over thousands of years, rely on a chain of stopover feeding grounds and habitats for breeding and raising young – but break any one link and the survival of the entire species is threatened.
Between our many residents and migratory species, birding in central Mexico is a joy. For example, I have commented before on how common names in English may make sense up north, but do not down south. But in the winter, both species head for Mexico. But it can also be a challenge.
Even the Latin species name soror (“sister”) indicates the similarity to another pitta species (blue-naped). The eBird description of the Small Niltava starts with the surprisingly dull statement that “size distinguishes this species from other niltavas” Who would have thought.
