Great Egrets at the Santa Rosa Rookery

By far the largest bird in the Santa Rosa Rookery is the Great Egret, and I’ll have to admit — though I know better — that I am always surprised that a bird this large nests in a tree — even if it always seems to be a very tall tree.  

On this visit, one of the highest nests I saw was this Great Egret nest with two chicks.

That seems like the most logical place for  Great Egrets to have nests since it is easier for them to fly in and out of the nest.

However, not all Great Egrets nest at the top of the tree.  For instance, this Great Egret landed near the top but had to weave its way through some awfully tight spaces to reach its destination —

So, I end up asking myself why did this egret build the nest so deep within the tree.  Do the dominant Great Egrets get to nest on the top of the tree?  Is it simply a matter of which egret started building a nest first?  Or is there an advantage to having a nest lower in the tree because it defers predators? 

I would love to visit Santa Rosa at the beginning of nesting and see which species start nesting first and where in the tree the first nests are built.  

Back to the Santa Rosa Rookery

Several years ago I discovered the Santa Rosa Rookery through Facebook entries, and I’ve tried to visit every time we’ve been in Santa Rosa during nesting season.  I thought that we might be too late to see anything on our recent visit, but I still drove over while Leslie and Paul were doing something else. 

As it turned out, most of the birds seemed to have already hatched and left the rookery, but there were still enough birds nesting that I spent over an hour trying to capture some shots.  

In previous years I tended to focus on the Night Herons, but I didn’t see a single Night Heron until the end of this visit.  The two juvenile night herons I saw weren’t even in the two main trees; they were on an adjacent tree.

The one on the left was certainly the more adventurous of the two and even spread its wings as if it was going to fly over to the other tree, but it never actually flew.  I only saw one adult Night Heron, and it was landing at the top of one of the two main trees, not where these juveniles were.

I was surprised that the Night Heron landed there because I’d just spent twenty minutes or so looking for Night Heron chicks and hadn’t seen any (which apparently doesn’t mean that there weren’t any there). On previous visits, the Night Herons, Great Herons, and Snowy Egrets far outnumbered the Cattle Egret, but the opposite seemed true on this visit. 

I’ll have to admit that I have a hard time deciding whether a chick is a Great Egret, a Snowy Egret, or a Cattle Egret, but it’s easy to tell when there’s an adult Cattle Egret in the nest like this.

These four chicks look a lot like those in the above shot and they were lower in the tree than Great Egret chicks I could positively identify, so I’m assuming these were Cattle Egret juveniles (particularly since there is an orange cast to the one trying to fly).

I’m less sure that these even younger chicks are Cattle Egret, but they don’t look like Great Egret chicks to me and I mostly saw adult Cattle Egret landing and flying nearby.

I’ve seen several rookeries since I started birding, but the Santa Rosa Rookery is the only one where I’ve seen such an amazing variety of herons nesting together.  

Our Last Day in Colorado

On our last day in Colorado Jen and the kids were busy getting ready for their upcoming trip to Puerto Rico, so Tyson took us on a much-needed walk before we started our long drive to Santa Rosa.  There weren’t quite as many birds as we had seen on previous walks, but I managed to get a  nice shot of a Northern Flicker marching across the field

and of a Great Blue Heron dining on frog legs.

With few birds in sight, I shifted my attention to the nearby flora and was delighted by the many flowers along the trail, particularly since I had no idea what they might be.

The only one that looked familiar was this one, which looked like a dandelion.  I’m not sure it really is a dandelion, though.  If it is, Colorado produces much bigger dandelions than the  Pacific Northwest does.

We’ve gone to Colorado so often in the last twenty years that it seems quite familiar, but it only takes a short walk to realize that there’s still much we don’t know about it. Of course, the same could be true of Theler Wetlands which we walk much more often.

East Lake 3 Park and Nature Preserve

There’s usually at least one day when we’re visiting the Colorado Websters when everyone is busy.  On days like that, I like to drive a few miles down the road to East Lake 3 Park and Nature Preserve in Thornton to bird where I can count on seeing birds I seldom see at home.

On this trip the first one we saw was a male Blue-Winged Teal, a bird I have only seen once in the Puget Sound area.

We didn’t have to walk much further to see a Spotted Sandpiper in the same area where I’ve seen one on previous visits.

I can usually count on seeing some American Avocet and found these two particularly intriguing because the one on the right was so much smaller than the one on the left and the two seemed to be together.  I wondered if the smaller one was this year’s chick, but the plumage appears to indicate it’s an adult, not a juvenile.

Studying the avocets did lead me to a nearby sighting, a Killdeer chick with an adult.

If my memory doesn’t fail me, this is the only place I’ve managed to get shots of Killdeer chicks.

About halfway around the trail, there’s a boardwalk that heads out into a forest of reeds that is full of Red-winged Blackbirds.   This juvenile Redwing seemed as interested in us as we were in him.

The male Red-winged Blackbird seemed more intent on seeing if we were a threat to his kingdom before grudgingly flying off.

There’s a small pond near the end of the walk where you can glimpse ducks and  Avocets up close if you can find a space between the dense reeds that surround the pool

We didn’t see the White Pelicans we’ve seen here in the past but I only noticed that while reflecting on the walk.  I was too busy seeing what was there to worry about what wasn’t there.
