Red Ribbon Wild Bird Seed available at Canadian Tire Stores...
Time of year you are welcome to feed the Trumpeter Swans: November to April (winter)
Tips: Sometimes you have to feed the little birds first or the bigger ones won't eat- Trumpeter swans are the biggest waterbird, so they are very very polite...
What's the difference: A Trumpeter swan grown-up has a black bill, a Mute Swan grown-up has a yellow bill...The babies called cygnets are very similar though, grayish with black beaks, although the Mute swan cygnets are slightly brownish-greyish rather than just ash-grayish...
What else could I feed them: Well we have tried defrosted organic corn niblets, freeze dried organic corn, whole untreated corn, different kinds of wild bird seed, organic whole grain breads from Whole Foods market...Sari has still not tried them on sardines or smelts, & was not thrilled with the Mazuri swan & duck food mainly because it seemed to have Northern Pike in it (which is in the shark family- little known fact) but also because this fish based food seemed too high in mercury(mercury is actually poop)- though this Mazuri food is what some zoos feed so it might be better depending on the batch & season...The swans found the shrimp pellets way too salty...They were not crazy for peanuts or black sunflower seeds, & the dried re-wetted wakame seaweed was not a hit either...Use your imagination...I imagine warmed wild bird seed, still warm (boil in some water) might be nice on a cold day (tastes pretty good with sweet & low & milk btw- that is for the humans who are tasting the food before feeding though)...
