Opinion
—Defendant/appellant Dante Carlo Ciraolo appeals his conviction of cultivation of marijuana (Health & Saf. Code, § 11358) following his plea of guilty, contending the trial court erred in failing to suppress the evidence seized during a search of his residence. The search was conducted pursuant to a warrant obtained on the basis of information gathered in a *1085 warrantless overflight of defendant’s residence. For reasons hereafter set forth, we conclude the evidence was inadmissible and reverse.
On September 2, 1982, Santa Clara Police Officer Shutz received an anonymous phone message that marijuana plants were seen growing in the backyard of a Santa Clara home, later identified as defendant’s residence. Shutz initially went by the house on foot and conducted a ground level investigation. He was unable to observe anything because of two fences that completely enclosed defendant’s backyard: a six-foot outer fence, and an inner fence аpproximately ten feet high. Officer Shutz undertook an airplane flight that same day with the express purpose of observing and photographing that portion of defendant’s residence enclosed by his fence. The plane was flown at an altitude of 1,000 feet. Without visual aids, Shutz observed and photographed a marijuana garden in defendant’s backyard. On the basis of the information obtained from the overflight, Shutz procured a search warrant for defendant’s home, and upon execution thereof, growing marijuana plants were discovered within the fenced area of the backyard and seized.
Defendant’s motion under Penal Code section 1538.5 to suppress the plants was denied, He contends the aerial surveillance violated his reasоnable expectation of privacy, protected by the Fourth Amendment and various provisions of the California Constitution.

The People contend the aerial surveillance was reasonable, citing, inter alia,
Oliver
v.
United States
(1984)
At our request both parties have discussed the applicability of
United States
v.
Leon
(1984) — U.S. — [
Defendant correctly notes that our primary focus must be directed to the
warrantless
search conducted during the overflight.
Leon
has no application to warrantless searches, nor does it overrule the “fruit of the poisonous tree” doctrine which first bloomed in
Nardone
v.
United States
(1939)
Further confirmation that the
Wong Sun
doctrine still controls is found in
Segura
v.
United States
(1984) — U.S. — [
We thus refocus our attention on the aerial surveillance of defendant’s residence, from which evidence was obtained to support the issuance of the search warrant. “The question to be resolved when it is claimed that evidence subsequently obtained is ‘tainted’ or is ‘fruit’ of a prior illegality is whether the challenged evidence was ‘ “come at by exploitation of [the initial] illegality or instead by means
sufficiently distinguishable
to be purged of the primary taint.” ’ ”

We disagree with the People’s contention that the federal courts have condoned aerial surveillance of areas within the curtilage.

Katz
v.
United States
(1967)
In
Katz
v.
United States, supra,
Allen involved the helicopter surveillance of a 200-acre ranch on the Oregon coast. The ranch paralleled the ocean for approximately one mile and was separated from the beach by a narrow strip of federal land. It was subjected to regular Coast Guard helicopter overflights for law enforcement and other reasons. The Ninth Circuit held that any resident of thе ranch, undoubtedly aware of the ranch’s proximity to the seacoast, the functions of the Coast Guard and the frequency of its overflights, could not reasonably entertain an expectation of privacy. (United States v. Allen, supra, 675 F.2d *1089 at p. 1381.) DeBacker involved a flight over open fields on thе defendant’s farm. No issue of surveillance within the curtilage was involved, and the court found that the defendant could not have had a reasonable expectation of privacy.
Other federal cases we have discovered which deal with aerial surveillance also distinguish between open areas or fields and the curtilage. (See, e.g.,
United States
v.
Marbury
(5th Cir. 1984)
Defendant’s backyard is within the curtilage; the height and existence of the two fences constitute objective criteria from which we may conclude he manifested a reasonable expectation of privacy by any standard. “The historical underpinnings of the ‘open fields’ doctrine also demonstrate that thе doctrine is consistent with respect for ‘reasonable expectations of privacy.’ As Justice Holmes, writing for the Court, observed in
Hester,
From the perspective of defendant’s reasonable expeсtation of privacy we deem it significant that the aerial surveillance of his backyard was not the result of a routine patrol conducted for any other legitimate law enforcement or public safety objective, but was undertaken for the specific purpose of observing this particular enclosure within defendant’s curtilage.
In short, we are not dealing with the observation of an open corn field which also contains a cannabis crop. We are confronted instead with a dirеct and unauthorized intrusion into the sanctity of the
*1090
home.

“[A] person need not construct an opaque bubble over his or her land in order to have a reasonable expectation of privacy regarding the activities occurring there in all circumstances.”
(United States
v.
Allen, supra,
Having determined that the area searched was within defendant’s curtilage wherein he could reasonably entertain an expectation of privacy, we must conclude that the warrantless overflight constituted an unreasonable search in violation of the Fourth Amendment. The fruits of that unconstitutional search cannot support a warrant.
The judgment is reversed.
A petition for a rehearing was denied December 10, 1984, and respondent’s petition for a hearing by the Supreme Court was denied January 23, 1985. Lucas, J., was of the opinion that the petition should be granted.
Notes
In light of our decision on Fourth Amendment grounds, we need not reach defendant’s remaining contentions.
Because Leon is limited to searches conducted pursuant to warrant, we need not decide the issue of its possiblе retroactive application to the instant case.
Clearly, the anonymous tip received by Officer Shutz did not, by itself, provide probable cause to support a warrant.
