Coldstream CA



Bloodroot, Sanguinaria canadensis, (white flowers above) is an early blooming native flower. According to Wikipedia:  "Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory. The seeds have a fleshy organ called an elaiosome that attracts ants. The ants take the seeds to their nest, where they eat the elaiosomes, and put the seeds in their nest debris, where they are protected until they germinate. They also get the added bonus of growing in a medium made richer by the ant nest debris."  Most of the ones I saw had tucked up their petals and leaves for the night. I would like to see a time-lape video of the opening and closing each day.

The bright yellow of  the marsh marigold flowers, Caltha palustris, are not captured by my photographs. The camera most auto adjust the colour, dulling it down. These flowers, although invasive, are a welcome sight each spring because of their vibrancy.
 




These eggs were in a pool of an intermittent tributary to the river at Coldstream CA.  I guess that they are American Toad eggs based on a description from a USGS webpage: "Toad eggs and tadpoles can be found in almost any aquatic situation, from muddy farm ponds to clear swampy areas, and are distinctively different from those of other frogs. Toads lay their eggs in long strings that may be benthic or entwined in (but not attached to) vegetation."

These turkey vultures were roosting in the spruce trees at the maintenance entrance on Coldstream Rd.  There has to be at least 20 settling in for the night.

Things are much more advanced inland than along Lake Erie. I think some things are a month ahead of last year!

So many shades of vibrant green today at Coldstream. Trying to soak it all in before it`s gone.

Blake, I agree with your comment about bad weather on weekends. I hardly got up the energy to go out today. Was glad to be there once I was out. Good to see blootroot. Lots going on despite the gloomy sky.
