It's been awhile since we posted. Sorry! We haven't given up our love for crows, life just gets busy. We are back now and look forward to posting more regularly. We saw this beautiful crow by the waterfront. I wonder what he was thinking about...such intelligent birds. As it is a Sunday, we will throw in a corvid stamp -- and start a new tradition -- Stamp Sunday! Hope you enjoy!
I have always loved crows. And recently I learned about the tens of thousands of crows that roost at the Bothell campus of the University of Washington. Of course, I had to go check it out. I don't think any number of pictures or videos I share will help share the experience with you. It is just something you should experience for yourself. They covered trees. They covered rooftops, they filled up light posts, the goal posts on the field. They flew around by the hundreds. There were literally crows everywhere. After dark, they descended upon the field itself with the lights shining down on them. It was like the most raucous, fun bird party ever. And they do this every night! The sounds they made are indescribable. It was really amazing to experience. Some might think it is straight out of a horror movie, but for me, these crows are fascinating. I was in awe for hours watching them gather. They met up like old friends and family at the end of their day. They flew in from every direction--from far away. While I was on my way to the campus I felt like one of the crows going towards the great meeting place. It was just really something I cannot explain well enough. I can't do it justice. I think I've found the place I will visit as often as possible. That said, here are some links for more information.

This is just too fun...look at him playing in the snow! They are such smart birds!
Caw! Caw! Or The Chronicle of Crows: A Tale of the Spring-time by RM, illustrated by J.B. It is a fun, lovely crow book. Lots of poetry with crows. This is well-worth the read. Try reading it aloud! =) If you dare, try reading it aloud AND recording it for me to post! =) I'd love that. Here are the first six pages... beautiful illustrations as well as fun poems. I will post the next six or so pages tomorrow. =) I hope you enjoy!

Crows and cats can get along... watch, You can even read the story of this amazing cat and lovely crow in this book Cat and Crow: An Amazing Friendship:
And more kitten/cats with crows...
A lovely albino crow... it is rare to be completely albino. However, it seems in my area a lot of birds are leucistic. I have seen SEVERAL crows with white streaks, white feathers. It is strange. I wonder if it is environmental in these cases?
I read an interesting article about corvids in Australia at The Conversation. I don't like to re-post full articles so, I will post a snippet and a link...
Corvids feature in the cave art of early humans. Their voices and actions reportedly stimulate human language and culture. Some research suggests that when humans interact with social crows, the things they see and learn can inspire their own rapid cultural evolution. Crows also seem to do things that people do (“talk” to each other, steal and hide things, use tools, “tease” other species, play), so it’s possible we’re all learning from one another.You can read the whole article here.
What a beautiful little bird! According to the Crater Lake Institute, four of the six birds mostly like to be seen at Crater Lake in Oregon are corvids: Ravens, Gray Jays, Stellers' Jays, and Clark's Nutcrackers (see yesterday's post about this clever little corvid!) Maybe we can nickname it Corvid Lake =). ((http://www.craterlakeinstitute.com/planning-visit/faqs/birds-crater-lake.htm))
A member of the corvidae family, Clark's Nutcracker is a lovely bird slightly smaller than the Spotted Nutcracker. It eats mostly seeds from the pine tree. And it has a pouch in the floor of it's mouth in front of its tongue (a sublingual pouch -- See below) which can hold up to 95 pinyon pine seeds (depending on the seed this number can vary from 50 to 150). To put this in perspective, 95 Pinyon pine seeds weigh up to 13% of the total weight of the bird!! How neat is that? They have a pouch in their mouth where they can store and carry almost 15% of their own weight! The Clark's Nutcracker also has a "long, heavy, sharp bill... used for hacking open green, closed cones, many of which are covered with pitch. Nutcrackers can open the green cones of most of the pines. The bill is also used to thrust seeds into the substrate with strong japes of the head and neck. As their name implies, nutcrackers can open thick-hulled pine seeds by crushing them in their bills."1 Most jays must wait for the cones to open naturally, but the Clark's nutcracker (and the pinyon jay) are able to open the tightly closed green cones. Lucky for them, they don't have to wait for a good seed.
In a year with a heavy cone crop a single nutcracker can cache between 22,000 and 33,000 seeds in over 7,000 individual cache sites (Vander Wall & Balda, 1977). Birds may place between one and 14 seeds per cache. Birds continue caching until the crop is depleted or snow covers the caching areas (Vander Wall & Balda, 1977). Possibly, birds curtail caching after snow remains on the ground because to cache in these conditions would reveal cache location by their foot prints left in the snow.2The Clark's Nutcracker possesses a number of abilities and physical attributes that help them thrive. They have excellent spatial memory abilities which allow these clever corvids to "learn and generalize geometric rules about the placement of landmarks." They use the landscape and even the sun (as a compass) to help them cache seeds. Their strong beaks help them crack open seeds, hence their name. Their long, pointed wings help them for strong flight to great distances. They can cache up to 22 km (a little over 13 and a half miles!). The Clark's Nutcracker "can carry seeds 1,900 m up the side of the Peaks."3 They use 'bill-clicking' which is the rapid opening and closing of the mandibles, to help determine if the seed is full as well as determine the thickness of the seed coat which saves time when seeds are abundant in the spring and summer. So intelligent are they, the Clark's Nutcracker can discern between pinyon pine seeds that have nut meet and those that are empty just by observing the color of the shell. WOW! Corvids are so intelligent! Sources:
