DEAR JOAN: Within the spring, I had sparrows that constructed a nest on my door wreath and subsequently raised 4 child birds. Now in July, I've one other pair intent on constructing one other nest in the identical place!
Is nest constructing widespread in July or might or not it's the unusual shift within the climate?
I stay within the Yosemite foothills, the place we skilled per week of temperatures within the 80s that may be very unusual for this space, the place the traditional summer season temperatures run 90 levels into triple digits.

DEAR MARCIA: Local weather change has all of us discombobulated, however the exercise you’re seeing now will not be uncommon.
Home sparrows can have as much as 4 broods a yr, spring by way of summer season. This very nicely may very well be the identical nesting pair you hosted within the spring, or it may very well be a brand new couple searching for a brand new nesting spot.
So long as you don’t thoughts the inconvenience of getting a maternity ward and nursery in your entrance door, there’s no hurt in it, and you may count on them to return season after season.
Not everybody likes home sparrows, nonetheless. They compete with native birds for nesting spots and nesting bins and have brought about considerations about driving out some chicken populations.
Home sparrows have been imported from Europe in 1851, when flocks have been launched in Brooklyn as a method of controlling Linden moth caterpillar populations that have been threatening town’s basswood bushes. Nobody realized, or presumably cared, that the birds wouldn't stay in Brooklyn and even the state of New York. Inside 50 years, the plucky little birds have been winging over the complete continental U.S.
Their numbers have declined in newer years, dropping from a excessive of 150 million within the Forties to round 7 million now. Nobody is kind of certain why we’ve seen a 95 % decline, nevertheless it’s suspected that the transition from farms to industrial use and concrete growth is the central trigger.
DEAR JOAN: OK, all of us hate it when rats race down our fences at evening, however right here’s my query: Do I discourage my canine from going after an evening opossum on the identical fence?
Opossums are well-known for destroying rat nests. These opossums are a nasty, snarling, fearless beast, however I’m beginning to like them. Canine disagrees.
Mark, Pleasanton
DEAR MARK: My canine would agree together with your canine, however having seen my canine make some questionable decisions, I’m skeptical of a few of his opinions. Though he was proper in regards to the Kardashians.
Sure, please have a chat together with your canine about leaving the opossum in peace. Of all of the wild creatures that go to our yards, the opossum is the least prone to trigger issues and the most certainly to be a profit, the rat evictions being only one.
Opposums eat cockroaches, rats, mice, snails, slugs and beetles. As a bonus, they’ll additionally fortunately glean over-ripe fruit and berries, however depart the good things for us.
Opossums have a certain quantity of resistance to the venom of rattlesnakes, in order that they’ll assist maintain your yard snake-free. In addition they eat round 5,000 ticks a yr. What’s to not like?
