Las Aventuras: Arizona Geese and Swans


A gaggle of geese

Today we'll examine part 2 of this blog series on Arizona birds, the Geese and Swans.  We'll discuss the rare and common birds and also who's countable (and not).  This is a fun group of birds because they are large and easy to see. To find them just head over to the many parks, farm fields, lakes and golf courses found around Arizona. And maybe, you'll discover something rare! So let's go on this goose chase and discover another group of birds found in Arizona.  



The Canada Goose.  Love them or hate them, they are quite common from the city of Phoenix on up to the northern part of the state.  They are often found around golf courses and parks in the Phoenix area all year round.  NOW.  If you live in Tucson like I do, they are VERY rare and not common at all.  Many Phoenix birders think it's funny when Tucson birders get excited about Canada Geese:) 


The Cackling Goose is to the very left.  Tricky tricky.....
The Cacklers.  Cackling Geese can be a major headache to ID because they are so similar to some of the smaller Canada Geese subspecies.  And within the Cackling Geese populations, there are ALSO subspecies.  To make things even more difficult, these miniature looking Canada Geese are often found mixed in with their brethren:)  Often ebird reviewers and birders alike need time to carefully look at the field marks before they "okay" their sighting.  These geese are always present every year during our winter months but in very small numbers.  Look for a shorter bill and a smaller bird.  It's even better if you have the Aleutian subspecies that has the white line at the base of the neck!   


Snow Goose
Okay.  Since I'm talking about similar geese species, let's look at both the Ross's and Snow Goose, both which can be found in Arizona during our winter months. 



The Snow Goose is much more common here during the winter.  To differentiate them, look at the "grin" on the bill of the Snow Goose. The Snow Goose is also larger with a bigger bill. Note the size of the bill on the Ross's Goose below.

Another fun wintering goose is the Greater White-fronted Goose.  I wouldn't say it's common but it's usually not too hard to find wintering in Arizona during the winter months.  


The Greater White-fronted Goose
If you play the ABA game, birds like the Egyptian Goose, Graylag and Swan Goose don't count. 


Seen in California not ABA countable
 However, from field experience, I can say that the Egyptian Goose is a species to watch and I think it's important to note the occurrence of this bird in the state for our records. If you are a true birder, you mark EVERY detail down on your counts, wild exotics included. In California, there has been evidence that these birds are breeding in the wild. Their populations are also increasing around the state.  This goose is not native to the US but has established several populations around the US. In Arizona, a few are seen each year in various places. 


Brants are usually found wintering along the coast of Southern California and very rarely get blown into Arizona by a big storm
But the sea goose that is rarest and most precious of them all is the Brant.  It will show up every great while at a pond or lake somewhere.  Sometimes, it's just for a day.  



Now for the swans.  There are 3 swans that can be seen in Arizona.  We have Tundra, Trumpeter and Mute Swans.  But here's what you need to know about these three species......


The Tundra Swan can be ID'd by the yellow lore on the bill
Tundra Swans are the most "common" of the three swans.  And by common, I don't mean often:)  But they have been known to winter in various watering holes around the state for the winter.  Some years are better than others.  But if you see a swan in the wild, the default is Tundra(or Mute Swan who has escaped the confines of a golf course).

Or even rarer, you might have the Trumpeter Swans.  Again, these birds are considered gems to the Arizonan birding community.  They can be tricky to ID and often throw birders off guard.  These somewhat similar looking swans to the Tundra can be one day wonders or stay for a week or more in the right habitat.  Proper ID is important here.  Tundra Swans have yellow lores and their bills are somewhat different from the Trumpeter Swans.  If you find this rare swan, consider yourself blessed by the bird gods:)


the invasive yet loved by golfers, Mute Swan
And finally, the Mute Swan.  It is not countable in the ABA world.  ABA listers get "ticked" when other birders count this "crap bird" on their Arizona list.  There is no right or wrong here but I will tell you that these birds are often captive and more than likely escapees from golf courses. If you ebird and are solely an ABA lister, you can enter 0 in your count.  Yes, you saw a Mute Swan but it won't count on your overall life or state list.  If you want this invasive swan to count, you'll have to go east and find one:)  And there are plenty.  



This is the complete list of "expected" geese and swans, but if you've lived in Arizona long enough, you know that crazy rarities have shown up.  Who knows?  Maybe an Emperor Goose will appear during a crazy weather event. With the right storm, anything is possible. I am bias, but if you are a birder, Arizona is THE place to live for all things avian.  Granted, I think birding is epic anywhere you go, but there's nothing like settling down after a trip somewhere and saying, "It's good to be back home with my birds."  Each Arizona day can shock and dazzle with a crazy surprise.  My Arizona series will continue on one of my favorite groups of birds......the grouse!  Stay tuned for more!

  1. I just came back from Copenhagen and saw lots of Swans within their city inland waterways. I see them in the Göteborg harbour and the lake behind my former house in Biskopsgården. Huge birds. But we watched a population of Canadian Geese of two building over the years now to about 20 birds. Young babies are always friendly, but adults still stand-offish when we feed them.

    1. I would love to see those swans. I think they are a new species for me. But to see lots of them in one place would be incredible! I'm always leery of geese and swans getting near to me....they can nab pretty well:)

  2. Fabulous set of images of the geese species. Wonderful to have sen the Brant. Our pale bellied Brent have arrived adn there will soon be about 30,000 of them at Strangford Lough. Quite a site. Have a great week ahead.
